Finished the upper six pounder guns. Had been avoiding these until I got to the step where I had to mount them. They were not really as bad as I feared. Problem I anticipated was drilling the barrel mounting hole in the end of the breech. Needing to drill a small hole in the end of about a sixty mil cylinder looked like a daunting task. But the white metal is a lot easier to drill than the plastic of the other guns. To help, I drilled a smaller hole first, the smallest bit that my pin vise would hold, then enlarging that hole to the #73 called for. The two pieces of PE mounting took as much time to bend and assemble as fastening the barrel to the breech piece!
The guns really look nice. I have them mounted now, to the boat deck.
