A couple of years ago I came across a sweet little Simson 28ga box lock sxs that was made before 1925. It is an American market gun as it was imported by a dealer in Washington, DC (name engraved on the rib). I found the dealer's contact info buried in a drawer and gave him a call--it is still available and I am going to take a look in a couple of weeks.
I don't have any pics, but from memory it has a Greener crossbolt, splinter forend with ebony tip, ebony drop points, English stock, small frame, 28" barrels with ivory bead, scroll engraving (50%+ coverage, weighs around 6lbs, 14" LOP, nicely figured wood, and rates at about 90%. It looks to be a very solid, unmolested gun in a rare gauge. It is nothing like the standard grade Simsons that are on GI.
I have tried to research this gun and cannot find any comps. The price is around $4,500. Any info or opinions would be greatly appreciated.
