When I was in college in the '60s I visited a gunshop in Macon,GA looking for something or other. They had a barrel completely filled with .410 and 28ga Spanish doubles priced at something like $75.

I picked a .410 out and used it awhile. Trigger pulls must have been 14lbs and I couldn't hit a dove off a telephone line with it.

I ended up giving it away and shied off Spanish fire for years. I now have a couple that seem alright.

My point is that if the gun in question is of the age I referred to it may be the same junk I found in that barrel...Geo
