Pigpopper ...you have a really nice rifle !I have loved the model ever since they first were produced...took me over 20 years to find my first one ( second hand),,,,and since then I have owned a .32, .40 custom, a .50 Georgia Treegun 24" barrel,a .54 Rocky Mountain with scheutzen butt plate and a 12 guage..... the Georgia is the only one with brass receiver..the rest are iron receivers. The mowreys have a 1:48 twist and handle conicals very well....Your gun is not stamped OLNEY which means it was produced by Deer Creek in Indiana who produced them when Olney Texas ceased...The lock parts from Olney guns will Not interchange with the Deer Creek guns with out hand fitting....I suggest you stock up on a few lock parts such as a stirrup and mainspring and sear ...you can still get these parts at Deer creek... They have no website you must call them by phone...765-525-6181 is the last # I have for them, their address is DEER CREEK PRODUCTS PO BOX 486 WALDRON IN 46182. I have never had to replace any parts in my Mowreys...but it dosent hurt to have spares just in case !!! Enjoy your Mowrey.! They have been out of production for awhile now and are getting to be far and few between ! The rifle is a copy of the ALLEN THURBER Rifle which was produce in the 1830's just after percussion caps were invented....it has minimal lock parts which means less things to break....which is a GOOD THING !!! Just before they quit making them they retailed for $450.00
