For the cost of Media Mail, anyone in the US may have two acetate reels, both displaying edge warp
and slight vinegar smell. One is Scotch 111, late-era box, about 2/3 of a 7" reel of tape. The other
is a complete reel of Ampex 611 (red oxide).

Ping off-list if interested. Postage should be south of $5.
