[Collins] Identifying BBs

[Dave Brown]

Thanks for the confirmation Jim and Jerry
Been a while since I saw one, and it looked a bit different to what I
recall-but my memory is totally untrustworthy as I have found out!
 The electros (there are a few others in the 32RS-1 like the one in the
picture) are all due to get chopped out when I get some replacements- plenty
of polyester replacements on hand for the BBs though so they'll get done
first.
