Old handcannon with smaller breech

[Lead Snowstorm]

Most of the noisemakers I’ve seen required a flash pan (as you mention) to hold the priming charge - this one doesn’t have a pan at all. And I must also admit I’ve not seen one of those upright noisemakers with a narrower breech - usually they were swamped wider at the breech to enable them to stand up. So I do agree this one is most likely not a thunder mug.

I cannot take credit for the stock - it came to me that way. I definitely agree, whoever made it did a great job!
