i have lots of these sights but non have aircraft serial No. on…
What slightly puzzles me is the Typhoon did not carry rockets until the end of 1943. It wasnt even in service properly till the middle of 1942 so thats fine for the MkIII sights but the 1941 MkII sighs as above must have been old stock converted.

Thanks Lance
I wonder if these were the original ones ? I read that W/C Beaumont originally converted a few MkII’s in the field, he later blanked out the adjustable reticule as well and just had a centre orange dot. Later still he did away with the reflector glass and projected the dot straight on to the windscreen before getting in to trouble with the top brass and having to revert back to the MkII

Lance at Corke aero has kindly supplied me with a gunsight body of the MkIII variety here for Rocket firing aircraft with a tiltable reflector glass to allow for drop on the rocket in flight

however if differs wildly from the version i already have

I cant find this version in any books so does anyone recognise this model ??

Yes, the graticule’s suffer because over time the rings seize up and people put a squirt of WD40 on them and that is instant death to the orange coating on the graticule lens. The first graticule lens with the propeller shape on it is orange plastic but the second is painted glass and thats the one that goes. Its amazing how many body’s have survived but bulb holders and reflector glass holders are proving really difficult to find…and as for the rubber buffer !! Hens teeth and i need two 🙁
