So, I'm the lucky guy who bought it - and having lots of fun with it. I've fired raw blanks - birdseed load and even one lead cannon ball. With lots of research, it has all worked out well. Would love to hear more from Marstar. Why have they designated it as antique? Why do they feel feel it is high quality steel barrel? What led them to determine it was shootable? Why did they advertise it as .75 cal when the bore is only .742? So much I'd like to know about it's history, but Marstar hasn't been answering my queries. I'm real happy with my purchase, but sure am curious about the claims made in the ad.
Very cool! thanks for sharing!
