Not getting much further on whether big-bore 1880-90's rifles used the Scott Gas Check patent.

But there's a second bug in my ear about this patent mentioned above, which no doubt the knowledgable members could answer. "Was the gas check patent only for use with black powder." i.e With the change-over to smokeless powders c 1900....did this obviate the need for the Gas Check?

I'm not a general gun historian but that patent might be sort of a marker of some sort if it were solely applicable to black powder.

1920's French Saint-Etienne SxS 12 bore shotgun - no gas check:
