Richland Arms was an importer in Blissfield, Michigan, until 1986. The guns they imported were mostly made in Spain or Italy. You probably have a replica of some Civil War era revolver. If it's Blonde colored wood it's probably a Richland Arms Co. Kentucky style pistol. I have a Richland Arms Flintlock rifle called the MICHIGAN rifle in .45 cal. and a wonderful rifle.The arms are rare now and were inported in the 1960's to early 70's. I assume the company is out of buisness now as there's no info to be had on them. The Richland caplock rifles were dangerous so I'm told by a master gunsmith and a friend. The Yorktown was named for blowing off the drum, stripping the hammer and chipping wood out of the breech area. .
