Tom, you are correct about Kraus doing the A3 and you know who's it is.
Jacob Glahn died in 1892 only spending 3 years with Hunter Arms Co. Not sure when the Spangle's left, but I seem to remember seeing their names in a who's who list in Futon after 1892.
I know that Glahn and the Spangler's did work for other companies like LeFever and SAC.

Kraus's work is good but looking at the setters, in my opinion A.E. Spangler's is better. I believe Wilson said the same.

Correction, Jacob Glahn Sr. died in 1902.
