I've kept restoration work to guns that were either very badly neglected, or incomplete. I've always tried to save guns that were in average condition by just doing enough repairs to keep the honest wear, and get them functioning properly.
I've only done complete restorations to three guns, with one more in progress. A Ballard #4 that was so pitiful that nothing but the receiver and buttplate could be saved; a Rem. Hepburn that came as a rusty action with a newly fitted barrel; a 1891 Marlin .22 that came polished out already; and the present project which is a Rem. #1 Rolling Block that came to me as just a complete receiver.
The Rolling Block is presently rebarreled, and wood was carved by Dave Crossno. Once I get the barreled action back from John Taylor I'll finish up stock and metal work, and then have the finish work done.
