I have a Minox 35 GL, which to be honest I had sort of forgotten about, bought in the late 70's or early 80's. I just pulled it out and went through things, still works. For some time I used it a lot, but of late it has sat in a drawer along with some other cameras.
I watched your clip right through, yeah, Elgar, don't give up your day hobby.
I too have never seen a hot shoe cover, or to be honest, didn't remember it having one; forgot that it had one until I saw you sliding yours off.
Mine has the orange shutter button, which was the colour for the GL. I think this is the quickest way to figure out which model one has with just a glance at the shutter button.
That delayed action button, or self timer as I thought it was called, is not on my model, could have been handy many moons ago for group shots when out walking and such.
The Minox flash unit was quite big, about two thirds the size of the camera and almost as expensive, maybe not quite, but it certainly wasn't cheap. I ran with a cheap generic Sunpak Auto 140 flash unit, which is almost the same size in bulk as the Minox camera, but for about $10 (at the time) so stupidly cheap, I bought two with the second one as a back-up as I thought at that price they wouldn't last. I never needed the back-up unit, so for a while I was using bellows on Nikon bodies and using both flash units for macro and sometimes micro work.
