I found this in my Grandfather’s attic this afternoon, I’m sure it’s some sort of RAF navigational aid, but can it be worked out which aircraft it came from?



It’s a Mk I plotter, the serial it says for those who can’t see it well, is 7237 / 4

That could be it, yes, I thought it was a / but it does look like a 41

Extremely unlikely and may in fact never have been fitted. Does the serial number end in 41? – that would date it to 1941.

I had an idea it would be. thanks Smirky.
Is it at all possible to pin down the exact plane via the serial, or is that an insurmountable feat?

It is from a big aricraft with a fixed chart table e.g. Lancaster, Halifax
