45K58

#F1015426, courtesy of John Langdon. For general saddlery, bag, portmanteau, cloth or canvas work. Drop feed, vibrating & climbing presser. Diameter of belt grooves 3 1/8” and 6”. Speed 700 s.p.m. Formerly known as 45KSV51 (and replaced 45K33 & 45K35).

 

45K54

#F1015426, courtesy of John Langdon. This treadle base came with a 45K54. The legs are 32" apart. The flywheel has a 1¾” diameter section and is 16” in diameter. Two belt pulleys: 11” & 14” dia.

 so, this is from the needle bar page. some info on the SV models here. and the treadle base ,as seen above, for the 45k54 was standard, so no bigger flywheel with the 45kSV99 according to this description. that leaves just the presser foot.

@jimi..There is a type of sail called "junk sail" that was not, and still is not usually sewn with a zig-zag stitch but is sewn with one or more passes of lock-stitch which would require a stepped foot to do. A lot of sail making of other types of sail was done with lock-stitch and multiple passes up to WWII.

I read a lot of sailmaker's forums in English and French, and have a friend ( mine of information ) who is one the major sailmakers for ocean going races, his loft is around 5 kms from me.

Btw..nice clear focused close ups..love 'em.. :))

Actually, graywolf, it's probably worth mentioning that again. I don't really consider that as speculation, as that very thing is mentioned in my original post. It certainly seems that some (probably not all) SV machines were considered good enough to put into production.

Jimi, nice find on that 45KSV100 corner stitcher. I always wondered what a machine would look like that could do that sort of stitching. Looks like I need to spend more time looking through the needlebar site.

I might as well repeat what I've posted elsewhere, as the info is relevant to this thread. My 111WSV77 looks the same as the 111W151-153 machines. The part numbers are all different (at least those that I could check) but it appears to match the specs of the 111W153 (foot lift/clearance/stitch length etc). I can't see any obvious differences, nor are there signs of anything else having been fitted - which doesn't mean something wasn't attached, of course. I'll try and get a couple of photos later (but the only difference to the W153 is the designation plate ).

Thanks dikman and Mike, junk sail?? maybe it was for this purpose?? good to know? that would make sense about the presser foot. if you see your friend mike you could maybe ask him? @Constabularydid you ever find out if the holes on the arm of your 29ksv3 were for the 2 big bobbins for binding? 

here is a video of an SV model:

I was told that also SV models were designated due to insufficient materials or different materials being used during WWII.  I don't have any way to confirm this but I didn't make it up either.  Maybe someone else made it up?

Jimi that guy has one heck of a nice little home machine there. Amazing the difference between home machines of that time and now a days. 

Gregg good info. I could imagine there would be some changes in material during WWII. I think most industries were affected by that to some degree. 

[dikman]

That's one of the big problems with this subject, Gregg, there have been quite a few statements made about the SV designation but they are almost impossible to confirm. I'm guilty of believing something that someone stated (about a 111WSV71) until, as I learned more, I realised that he was probably only repeating something that he himself had heard but actually had no idea himself.

As far as I can figure SV's were made before, probably during and after WWII, but that doesn't necessarily mean that your statement is incorrect. Just another piece of the puzzle. Meantime, a couple of photos of my 111WSV77. I'm guessing that the additional number plate suggests it may have been part of a very large company.

dikman - at least your feed dog and needle plate look like the ones from a needle feed machine like 111w151

Regarding wartime machines - I know from some Adler machines of different types that the war time produced machines had fewer chrome or nickle plated parts. Some parts where black instead and the casting was much rougher. I once have restored an Adler patcher which even had a sticker or decal on it that this machine was produced in wartime. This has nothing to do with Singer SV´s but maybe explains why your machine has a black iron model # tag instead of the common brass tag.

It's a real pity that the records from the Bridgeport factory don't exist, as it makes it extremely difficult (if not impossible) to try and date the W machines, or even try to put them in some sort of context. As to my machine, part of me says to strip it and refurbish it and another part says to leave it as is.
