Mr. Cate gives Sauer #103,221 as a Model 11 for retailer "EWD. K. TRYON JR & CO. PHILADELPHIA" and notes the Krupp Fluss Stahl tubes "are marked PRUSSIA and have 2 quality Crowns showing." but he doesn't indicate if they are together.

Then on Sauer #110,084 he gives it as a 12 bore hammergun with "Prussian crowns(one larger than the other on the bottom of each chamber area." which I take to mean that the crowns are separated.

Kind Regards,
