I assume it has a Cimarron address line ?
I'm somewhat with Pettifogger on the ASM Richards conversion
, however it is outside the normal, and quite nice, judging from the photos.
Perhaps, something Harvey had Dave Anderson do
. The dove tail sight is unique, both Anderson, Kenny Howell were known to do these.
I can't quite tell, the ejector rod seems be of the larger Diameter , than the normal 1/8" ASM rod
It appears to have a screw in the hammer for the Uberti style hammer block ( Custom Uberti ? )
The silver plate & engraving is Anderson'ish ....The high gloss grips are not, also the CHC is not as vivid as I'd expect on an Anderson gun.
I assume no other markings , perhaps very small letters under the barrel quite close to the ejector ?
Interesting and unusual piece, you did well
