Being Scottish, I love a bargain and I found this strap in a box in the loft. It was on a compass that you wear on your wrist like a watch. No idea where I got it from, lost in the mists of time!
It's a one piece one, with a kind of woven finish. There are no strap holes and you push the pin through wherever you need it, so it fits very well.
Trying it out on my 1968 600ft, which I think it matches well.
What's attached to your wrist today?
