Doc Drew were the L.C. Smith Top-Action Double Cross-Bolted Breech-Loading Double Barrel "Bar Action" used only on the hammer models or were they also used on the early hammerless guns as well. I haven't go the intestinal fortitude to pull the locks off of mine to check.

By the way the Quail are starting to pair up and the Roosters are starting to sing a bit. So far it looks like a decent breeding spring here in North East Kansas.
