Putting this here as it's not a watch or a clock.

Picked up this Smiths timer, have no need for it but I just liked it!

It's marked as manufactured by English Clock Systems on the back. It's got a lovely slow tick.

It works well and resets cleanly but I'm going to strip this down for a gentle clean and polish.

Does anyone know a rough age? I'm thinking 60's as still marked as Made in England. I see them described as darkroom timers?

Thanks
