I hope you don't include your old neg files in this!
#1 Scan them. There is stock selling that can be done.
#2 Sell them. I've bought old neg collections from the 30s, 40s, 50s,

I need one. Badly.

Some old SMC Tak lenses, perhaps? I wouldn't mind. @

he's been called.

At least categorize the goodies. I'd surely find something of
interest!
Where do you live? Going to be home for the holidays?
