[Austin W Hogan]

The grade may be stamped above and/or below the serial on the water table. 0 and 1 grades may not be marked. The grade may be inferred from barrel steel or engraving pattern but the lowest grades are not consistent.

Clean the barrel mating surfaces and frame thoroughly. Remove the extractor and thoroughly clean the extractor and its recesses and tunnel before attempting any work to tighten the action. This can usually be done with Hoppes, Q tips and patches.

The checking can be cleaned with Murphy's soap, a soft brush, and a soft rag.

Best, Austin
