Don Bosco Electronics Stethotracer and Mosquito / Production year(s) ??



Jan 1, 1970
I have a Question on Don Bosco Electronics Inc., which was located
Littell Road and/or 56 Route 10, Hanover N.J. - USA

They produced the " Mosquito" and the "Stethotracer" ( the latter with
a load of adaptors ) and all still in good shape, both of which are
still in my possession, and will be transferred to SIWE (
), the Belgian Society for the Preservation of Scientific and
Industrial Heritage. About six tons of my equipment and docs. are
already with SIWE.

The Question is: What year(s) were these items produced; no trace of
year of production in the documentation of the Stethotracer.

If anybody could still get me a copy of the manual of the "Mosquito",
I would be thankful.
- This as all the other stuff went to SIWE with complete

Thanks in Advanced for any Reply.
