Thanks.These are swiss made by a company WILD Heerbrugg, which went bancrupt in the 90s. For some time, Zund has done service for that machines, but not anymore.
If needing spare parts or help, you can try to contact www.mucad.com in Austria.

Trying to find an email address to contact them, but so far haven't really found that info on the webpage. Will keep searching...
The electronics and mechanics of a TA10 and TA41 are completely different. Not even the pen and blade holders are the same.All the WILD, WILD-LEITZ, LEICA TA's are fairly similar from what I recall.
I used to love running these things...
