Hi guys

Went to an auction and actually found some nice items here in rust world. But 
there are a couple of things I am wondering about:

1> Saw  is a Disston & Son  (no s)  interchangeable style split end blade 
with an 1874 patent  date in a Disston & Morse handle that is a bevel / 
square style , sorta like somebody took the bevel blade out & made a  strange 
pad saw like tool. Any body seen this before?

2> a cast iron bevel like the early Stanley #18 but not marked or plated. The 
bevel blade is marked Sargeant and has an 1872 pat. Did Sargeant make these 
also ? 

3 > The third object was put up as a "saw set" which it is not but has a 
hammer and cam set up that whacked something when you turned a handle. Neat 
with brass, japanning and nickel. Anybody heard of  an E. E. Cunningham Corp 
that had a 1874 patent for weird hammer thinggys  ?
