The barrel lens... could it be front mounted? If not, maybe you can trade the whole thing for a Packard shutter with somebody who wants the #1.
I don't think the barrel lens could be front mounted - it's almost as big across as the whole shutter (it's that one I showed you and the crew at the Quabbin a few years ago). I could go for a trade for a Packard, if anyone is interested. I'm not in the financial situation to buy one, but trades are cool (even if minimal $ has to be added).
