At work with cartridges and arms back then

Check that hair and that sweater… Not to forget the moustache. The hair is still there, well at least most of it, the sweater … who knows? The moustache is gone since long! Designing products and having cartridges and tone-arms made is one thing. But there is a lot of work around. Checking, packaging, and in this case “drilling” all under heavy control of daughter Petra.
