Sutton 600 "Lockstitch" Machine??

[Cumberland Highpower]

I happened to look over a Sutton Mckay 600 stitcher and a 600 manual    I've never really had much interest in this type of machine, but was still curious.   

What intrigued me was the heading on the manual.  "Lockstitch Combination Machine"   and a picture of what appears to be well, lock stitching.

 

I guess what puzzles me is how can this really make a lockstitch?   Is it a true lockstitch or a chainstitch that locks a bit more than usual?

How would it appear on both sides?  Appearing as a true lockstitch or something else?

I was also lost a bit in the fact it only had a hook, and no awl.  Seems that it would struggle to make clean "punctures" in most any leather?

Anyone have any experience with this exact/particular machine?   Maybe some detailed photos of work done on one to showcase?

I don’t know anything about this machine, but I’m fascinated by antique sewing machines and I’d love to see some photos if you don’t mind sharing them. I look forward to following this thread either way.

Alfredleatherworks, In a way I'm slightly ashamed I know very little about these types either.  Never really dabbled with shoes/boots....But I might be able to cook up a need for one if I try? This is just a random photo of one I found on ebay to cut/paste here.

I’ve seen machines like this  in use when I visited a boot & shoe shop in Uruguay last year. They’re amazing machines! I don’t do boots and shoes (though I’m learning in my spare time for fun), but watching folks that do it every day run one of these machines was absolutely enjoyable and educational. 

This was a clone of the Sutton/McKay/Landis machine I think? They had two of them.

And this one is an old, old, old version whose make/model I cannot recall. They had two of this machine also.

They of course had other cool old sewing machines there too, and I took photos of all of them. I showed up to buy needles for my 341 clone and ended up with a tour, lol.
