Got two. One is a Daly 500 12 ga with original 28" barrels and a retrofitted set of 30" Miroku-marked (non-Daly) barrels with their own forend. This one is PG/Splinter/DT/2-3/4" chambers on both sets, looks like the one in your pic but has oil-finished wood now.
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". The frame is not really a fancy back, but the metal is convex with nicely fitted wood. The 12 has a square back like your pic. The 20 came with what appear to be original white line spacers on the grip cap and butt plate (not pad). I have thought about removing the spacers, but they will come back some day, as will leisure suits.
Both are very nice guns, extremely well made, and handle differently from somewhat comparable BSSs. Lighter barrels and nicer wood than the BSS, and finer checkering as I recall.
