Sorry about the rather long post; I thought I'd go through my OM kit.
Olympus OM-10 body, one of two that I own.
The other, with manual adaptor attached
I can't remember why I bought the second, but I think it had something to do with wanting negative film in one and slides in the other.
Zuiko (Olympus) standard 50mm lens, usually supplied with the OM-10 body.
Another. Note the bare metal on the filter mount screw-thread.
It had been mounted on one of the OM-10 bodies, in turn on a tripod with a jacket thrown over it to stop it heating in the sun. It was a calm day, but a freak gust blew the whole lot over, denting the filter mount. I thought that would be the end of it, but some years later, an engineer moved in next door to dad. He turned out to be a camera collector. He took one look at it and said "no problem, we'll have that in the workshop and fixed in half an hour." I watched, amazed, as the guy carried out some very fine and delicate "panel-beating". Carefully, he fettled the thread and inside an hour had most of the filters fitting.
2x convertor, OM-fit
Cumbersome 75-200 lens with power zoom. Very 'eavy, very 'umble. Can't find any reference to it.
Sigma 28-70mm OM-fit
Optomax 35mm OM-fit
Miranda 24mm OM-fit
Careworn Olympus T-32 flash unit
I had the whole of this lot in a gadget bag (the one I still use) with an assortment of filters and accessories plus tripod (again, the one I still use) and carried the lot 200 miles across the Himalaya back in '95. I had a rucksack on my back, probably about 25-30kg and the gadget bag weighed in at 6kg which I had to hold in my hand. It's a wonder my knuckles don't drag the ground.
Imagine walking up Ben Nevis and down every day for three weeks like this in air at 2/3 pressure. I was fit as a fiddle when I got home.

To date, the last photo I took with my OM kit, October 2003, Thomas Telford's Menai Bridge, carrying his A5 London-Holyhead route from the mainland to Anglesey.
