Their tiny .44XL and .410-bore hammer guns were truely tiny. The hammerless .410-bores were really on the 20-gauge frames. Sometimes they belled the breech end of the barrel to match the 20-gauge frame and later just left them incredibly heavy.
If it is a .44XL, I would be interested if you want to sell it. If .410, can you see any patent markings on it? Have you checked the chamber lengths? Current research says that Parker offered the 1st American built .410 sxs. I have long felt that there was a possibility that Crescent may have beaten them, but it is not documented. The 1st American built .410 single shot was the Stevens, with a patent date of 1915.
