Not odd but I did get to shoot the MA deuce.
We mad a tennis ball cannon out of an old driveshaft, propelled by oxyacetelene. Light the torch, get a good mixture then put the flame out on the ground, through a hole in the lower half of the driveshaft put the gas mixture, count to 3 was about right, 200 yards, more than that 50 yards as the tennis ball came apart.
2 liter coke bottles filled with the same mix, duct tape tail and a shotgun primer with a BB glued to the cap on top of the primer, make the windows shake for a full city block.
Now something odd that I own, a Daisy VL caseless ammo rifle, only made in 1968.
