Does anyone have or have they seen or do they know where to find CW era plans or drawings of a 12 pdr. coehorn mortar? Lutz's AOP book listings do not have any for the 12 pdr. coehorn.
I did find 'CU Cannon's' post of Nov.19,2005. In that post he had drawings of a 12 pdr. he scaled down from a 24 pdr. Union coehorn mortar. Those drawings show the bands the 24 pdr. had. I do not believe the North made any 12 pdrs. only the South. If that is so I would think the Southern 12 pdr. would have straight sides.
