Hi there,
I have in my possession a Smiths Mk19B altimeter in working condition, and I gather these were used in many RAF types. I gather the hunter F4 and F6 used them. I suspect mine came from AST at Scone, which at the time, there was a Provost T1, Hunter T7 and Trident there. The alt is calibrated to 50,000ft, which rules out the T1!
P/N 6A5040, Code Number KAA-0806K, s/N NS5757.
Anybody got any ideas?
Cheers!

The Provost T1 that I helped to rebuild in 1979 had altimeters 6A 3380 (new ref – 4333298).
Using your logic, I suppose 50k rules out the Trident as well?:D:D
Well, the trident isn’t completely ruled out. I work a lot with pressure guages, and I am led to believe these are most accurate at mid scale, so on this logic a trident may qualify. But as not being an ex RAF aircraft, this does discount it a bit. The company I used to work for had a fair bit of avionics from Trident G-ARPP which was scrapped in Glasgow, hence the hesitation in identification. The altimeter was stored away from the Trident avionics.

Introduced in the early to mid 50’s and fitted to a wide range of types after that date.
The Smiths Mk 19B was designed to a price;- single capsule, minimum parts count and alloy gears…… as opposed to triple capsule, the right number of parts required to do the job properly and bronze gears.
Compared to other Alti types it’s a piece of junk.
