Triumph #1 weird.

Found a Triump #1 that I ain't never seed before.







Triuph #1 that has the pan offset to one end, it also has a strange piece with sides that have a hole in them added on and this piece also holds one end of the jaws, it won't allow the spring to sit flat so no idea what it was for. There is also an S hook on the frame between the pan and the weird piece.

It looks to me like the frame is for a "Three Jaw".

I kinda/sorta thought so too, but the only triuphs I can find online have the third jaw thingy inside the jaws. What the heck would the S hook have been for?

I was thinkin a Triumph longspring cross added on a Triumph Easy Set base.
No idea why the S hook
The original owner must have been desperate to get a #1 working or maybe just bored during one of them long Alaska nights...
