10 Gauge Weight

[ArtS]

What is the weight range of 10 gauge guns?

I mentioned that I had recently bought an 1874 Parker lifter in an auction. The gun was listed by the gun dealer as a 12 gauge but when I looked up the number in the serialization book, it showed it as a Damascus 30" 10 gauge. Grade looks to be above a base grade but below a 3 grade like I own. The barrel specs met the listing notes, so I questioned the dealer and was told they had tried a pair of 12 gauge snap caps and they seemed to fit OK.

I won't recieve the gun until next Tuesday, but I requested a letter which came today. It stated the gun was a 10 gauge built in 1874 but no mention of the chambers in the stock book (Number 1). No order book. The rough barrel weight stamped on the barrels in the ad shows 4# 2oz. I have a 3 frame 10 with 30" barrels that are marked 5# 10 oz. That gun weighs 10 #. That would seem consistent, but would a 10 gauge normally be found that light? I am thinking this might be a 10 ga with 12B brass chambers.

Some bore and chamber measurements will be in order as soon as it arrives.
