Default Re: ENIGMA machine being auctioned.

Original circuit for reader part of the tape electronics of Colossus.
Hope it displays ok for forum readers.
The valves are EF36.
Note the date, an amazingly early 1943, and reference to Dollis Hill.
I was looking for the historic initials of "T.F." but the original was trimmed on the LHS table of amendments.

Craig will have seen this, as it is on the wall behind the Colossus rebuild at Bletchley.
And by the way, congratulations on your great work with the rebuild of the Lorenz SZ42.

(Any chance of my dropping by and pick up one of those AR88s please? The one at top left will do).
