Image came from eBay .. of course, not posting the auction, as it is live at this point.. doesn't seem to have alot of bids, though not sure why.. what a priceless find!
Wow. It does make you wonder what is under all that gunk. If it's in decent mechanical shape it may not be a bad deal. Certainly one of those gambles though.
If in good mechanical shape it may also be a good candidate for replating as some have discussed here.
The silo door on the right looks like it might have corrosion on the safety bar edge. That would be a problem.
From the image, it's hard to tell if the silo doors are just covered in gunk or actually having a corrosion issue.
I found a Gillette Tech this week that was in no way shave-worthy without some heavy metalwork. The dealer was asking $80 for it. I saw it and the price tag and started laughing. That got me a dirty look.
