Ok, here are some more close up pictures. You will note that it is missing some bolts, pins, etc., because it all has to come apart someday for painting.
A question was asked about sealing riveted boilers. Yes, they needed to be sealed with solder.
I should have mentioned that I shear rivets to length, if they are small ones, say 1/8" and under with one of those electrician's crimping tools that have holes to shear threaded screws off. I drilled a couple more holes in it with a carbide drill. For larger rivets I made a shear out of a automobile leaf spring that works the same way as the electrician's tool. Sawing is so slow, and clipping them with diagonal clippers leaves a wedge shape end.
