Here is my winged emblem Collins 312B-4 in absolutely mint condition. I’ve had it for many years…it was bought from John Wilson of Lowe Electronics fame.
I’m only replacing it because I bought a full round emblem S Line which includes one of these.
It truly is the best I’ve ever seen…genuinely mint, like new.
It comes with a copy of the manual…there are no cables included as John never sent me them. They are simply screened cable and phono plugs etc… so are easily fabricated.
It’s very rare to find one in such perfect condition, and I think £290 plus £25 postage and packing is a fair price.
Here are the pictures:
