I think a good number of us would like to see what it looks like, just out of curiosity. Maybe post it? (Erez, would you like to? James Redin?)

Btw, a photo of the innards of a Bohn Contex would be very interesting.

Hi friends,

Here you are.

Sorry for the quality of the photo and of the machine. But the machine works fine.

Regards,

Peter

James,

I include a scan of a Numeria brochure, apparently printed in 1960. It seems to be a stepped drum machine with two versions available. In the 50's

Numeria also had a British currency model, but if it was still made, it is not advertised in this German brochure.

Dear James

Sterling single rotation cam driven machine in Sterling?

Such a machine would be interesting to say the least. How gears of 12 pitch (Pence) and 2 Pitch (10/-) could mesh would change all my ideas on mechanics. Remember the carriage moves across to calculate in lower or higher orders. This means the body of the machine must mesh in all positions with the carriage. A very difficult proposition in a Sterling machine.

If you ever find details of how this can be done on a single cycle cam driven machine I would be more than interested in knowing the mechanical details.

Loved the picture. It looks like a copy of the early manual MADAS machines, and I guess many others of the period. It the fifties Italy started manufacturing many such copies due to a special export drive iniative by the ltalian Government. Not unlike the AE (American Export) 1970's drive of the American Government.

Regards

Hi James,

in the meantime I got some information about my Numeria. Friend and typewriter-collector Peter Muckermann sent them to me. In the enclosed TIF-file you find a copy from

Büromaschinen-Lexikon 1958/59

office machines handbook 1958/59

My model seems to be the no 7203 H. Please notice that in those years 1$ was about 4 DM.

Regards,

Peter
