Second one is a 20 ga Miroku 500 (not Daly-marked), 28" barrels, F/M, PG/Splinter/DT, don't remember chamber length but probably 2-3/4".
Is that non-Daly Miroku actually marked 500, Replacement? None of the doubles I can recall looking at, if only marked Miroku, aren't marked 500. I think that was strictly a Daly model designation. Quite a few Miroku models seem to have had a letter designation. For example, I owned a 12ga Miroku Model M. Straight/splinter/DT, case colored receiver. Looked for all the world like a very basic Birmingham BLNE. That's one I put in my "wish I hadn't parted with it" category.
