Here is the belly of the beast. The 2 inner skirts are in the best condition I have found to date. Originally I thought these were used on the same line as I had been finding the U-913a's (previously unlisted), but the time periods do not match as the 913a's are likely 20 years newer. So now with my previous theory thrown out, it is quite possible I may have some new places to look for more Boch's. Will I ever find a whole one? Probably not :) Our harsh Ottawa winters and severe freeze-thaw cycles cannot be kind to these very fragile dry-process insulators.

For anyone who has never found one of these, they weigh a TON and are not fun to carry around through the dense jungle of brush and vines where I have found them all!
