oldtimer Report post Posted July 18, 2009 What is the difference between a Singer 45K21 and a Singer 45KSV49 ? I already have a 45K21 and I found a 45KSV49 (on a treadle stand) at a price I could not resist . Are parts interchangeable between the two machines? There were a lot of parts in the deal, more than 100 needles, 3 different roller feet, 7 different presser feet, 2 shuttles , different needle plates , 15 bobbins, a needle bar and a lot more. I´m really happy with the deal! What does "KSV" stand for ? and are the parts in the two machines interchangeable? / Oldtimer Quote Share this post Link to post Share on other sites
CowboyBob Report post Posted July 20, 2009 The "K" stands for UK as in Made in England,the SV means special version that only Singer knows what it was made for they changed a few parts for a special application. It's good you got some extra parts since they are getting very hard to find. Bob Kovar Quote Share this post Link to post Share on other sites
oldtimer Report post Posted July 20, 2009 Thank´s for the info, Bob. Yes, It is good to have spare parts for these old warhorses. I am looking forward to recieve the "special version" 45. / Knut Quote Share this post Link to post Share on other sites

Bob Kovar Almost, but not quite. The 'K' actually stands for 'Kilbowie' the factory Singer once had at Clydebank in Scotland. The letter codes on Singer machines always denoted in which factory they were built. 'W' was the old 'Wheeler & Wilson' factory that was taken over by Singer, 'G' was for the factory at 'Karlsruhe' in Germany (they had already used 'K'), 'U' was for 'Utsunomiga' in Japan. There were several other factories, all over the world, each with it's own letter code. The only Singer machines without a letter, just having a hyphon, (such as the 17-16, or 31-15), were made at the original Singer works at Elizabethport, Elizabeth, New Jersey. I have a couple of 45Ksv100 'Box' stitchers and a 16Ksv21 light weight 'box' stitcher, but I've never seen a 45Ksv49 and would be very interested to see one. Any chance of a photo?

Strange, but the metal sign on the machine says KSV49. / Knut Edited July 20, 2009 by oldtimer Quote Share this post Link to post Share on other sites

That is correct, the Singer site lists very few of the 45K sub classes that were produced over the years. The SV (Special Version) sub classes are particularly difficult for which to find info. I've been trying to locate data for ours, for some time, with no luck so far. Singer produced the SV machines in very small numbers, compared with their regular machines, however, if a Special Version proved popular and many more were sold, they would change the number and drop the SV designation.

oldtimer Report post Posted August 5, 2009 Picked up the machine today ( been on a vacation in Denmark last week) and cleaned it up. The most obvious differences are : The flywheel is heavier on the KSV49 than on the 45K21 and the needle plate is flat on the 49 and domed on the 45K21. I threaded the machine and .... it sewed perfect (without any adjustments,) better than my K21, so they changed places in my shop. / Knut Quote Share this post Link to post Share on other sites
Double U Leather Report post Posted August 6, 2009 Just out of curiousity, what did you give for it? I got a 45K with the domed sew plate this past spring for $250. After a few minor adjustments, it sews like a champ. Thanks to Bob at Toledo Sewing, I now also have a machine with a flat foot instead of a roller foot. Bob, the new arm and foot work beautifully. Thanks. Quote Share this post Link to post Share on other sites

CowboyBob Report post Posted August 6, 2009 Wayne, I'm glad the hear you got your machine going, Knut,that's a great buy & it's even better if you get extra parts as those flat needle plates are almost extinct here. Quote Share this post Link to post Share on other sites

Bob, on the pic there is a needle plate with a guide and the feed dog for this plate. The needle will barely touch the edge of the material. What is it used for ? Also, the conical "thing" to the right, what is it ? / Knut Edited August 6, 2009 by oldtimer Quote Share this post Link to post Share on other sites
CowboyBob Report post Posted August 6, 2009 I've seen them on other machines like the champion & landis #1 have them & there called pricker feet,they push the thread down deeper in the stitch & they are matched for your stitches per in so you had to match the foot w/stitches pr in. I've never seen this part for a singer 45K,does it have a singer part # on it? Quote Share this post Link to post Share on other sites

I've never seen this part for a singer 45K,does it have a singer part # on it? There is a number : 91790 on the bottom side, (no "SIMANCO" label), and on the raised part, attached with two screws and with the square opening for the narrow feed dog, the number is : 91791.

CowboyBob Report post Posted August 7, 2009 I look through some parts list I have & have a feeling that it is a Singer # for both parts but I can't find them,so if you ever found a parts manual for the 45KSV49 you find them in there.That's probably what made it a SV machine Quote Share this post Link to post Share on other sites

I would only be guessing as to it's original use, particularly with all those fantastic extra parts! The only thing I can think of, mainly because of the flat needle plate, is that it may have been designed for some specialist harness making purpose. The range of roller pressers seem to indicate the need to get very close to the edge of something. Steve Quote Share this post Link to post Share on other sites
oldtimer Report post Posted August 10, 2009 (edited) Today I traded my old doghouse and kennel net ( dog moved to dogs heaven a while ago) for a modern Singer sewing machine stand and a clutch motor. Good trade as both of us thought we got rid of old junk ! Took the table from the treadle stand and put it on the "new" stand. looked for and finally found a speed reducer I knew I had "somewhere", so in the next few days I´ll have a second 45K motorized and running. I´m still wondering of the use of the special needle plate in the box but I guess it is that part that makes it a Special version!? / Knut Edited August 10, 2009 by oldtimer Quote Share this post Link to post Share on other sites
