Interesting. I apparently have two of these Aerovox caps, though not from
this dealer. They were $75 each from ebay as I recall. They are made in
1980 and 1981, all paper construction, the high voltage terminals are
crumbly but seem to have survived a few dozen shots. Mine arrived with no
grey lacquer left at all (rusty), but it's no big deal. I have no way to
know if they are used, or old stock.

Modern equivalents are about half the size/weight from what I gather.
