William Robertson was a Gunmaker that had a shop next door to
Krider. My reference books have him out of business @ 1860
Hard to know when gun was made as Krider copied many gun actions
-this is the only gun of his I have seen with proof marks and
they are only on the BBLS
This gun is about as mint as it can be-with "hard" vivid
case colors-if ever fired was fired very little
Thanks for the info
Bill
