Degrunging

The Model 12 is now clean.

There was some serious funk up inside that receiver, including a large dead and desiccated winged ant.

Did a detail disassembly, took off all the gunk, gave a nice light coat of oil and all is once again as it should be in the universe.

By the way, I've seen NEW bores that didn't look this good.  Despite the build up of crud in behind the bolt, the bore was meticulously maintained.
