List of historic thunder mugs at Rock Island Ordnance Museum 1909

[cannonmn]

One of mine is very close to no. 2810, except mine is marked "27 Lbs." and is 8.5 in. tall (also has 1.25 in. bore.)

The gas pipe cannons are also interesting-they were a curiosity and a big deal early in the 20th C. and Bannerman's had fairly high prices on theirs.
