-A picture of said piston & numbers would be helpful.....
By: 8th April 2012 at 20:51 Permalink - Edited 1st January 1970 at 01:00
-As has been said a photograph would be best but failing that:
- diameter of piston crown?
- description of crown: flat, domed or concave?
- description of underside of crown: smooth, ribbed (insert condom joke here) or other features?

-Sounds a very interesting find you have made. As everyone states, "A picture paints a thousand words"If anyone can I.D. it, given what is asked, then C.D. is the chap, he has I.Dd. several for me.

will take few sizes with the old tape when back to work. pretty sure top of piston is flat but with concave dip with a nipple (insert joke) in it. something to do with combustion?. also, parts of piston rings are just gleaming. would these be white metal? hope photos to come are of help too. cheers . s.:D

Sounds like a diesel piston...

Not white metal, if they are gleaming, most probably chrome (plated); it is sounding like a diesel piston to me.

hi again, was afraid id hear it might not be an aircraft piston but hey ho! wasnt able to take pics today but jotted down a couple of sizes and numbers that are legible. they are as follows: approx 107mm dia. x 120mm high or imperial equivalent. metric rule used sorry. numbers: BLPV 100080?? 703F-61??.

Sorry, way too small for any serious aero-engine (unless you count Napier)!

cheers CD. i actually thought it was a bit large for an aircraft engine. shows how much ( or little) i know!! . as an aside, the hanger in which i work at ex raf evanton used to have some lovely aircraft recognition posters on the wall, which some clown saw fit to paint over. some folk just dont get it!!

I’d still like to see a photograph of your piston if you can post one.

hi there, according to some bumf i found, the closing date for the airfield here was march 1948. this obviously means there were no vampires based here. any suggestions?

-Vampires were operational from 1944, so no reason why not!

many thanks for your reply bruce. wasnt at all sure when the old vampire came into service wrongly presumed it was later than when raf evanton closed. im delighted because i couldnt tie it together otherwise. the literature states all the aircraft based there before, during and after the war. this obviously doesnt include the vampire, though i suppose it makes sense they could easily have been visiting, on detatchment etc?.

hi all, i work in a converted wartime hangar and recently a workmate lifted a metal floor plate and found the top half of a piston. ever the romantic id love to think its from one of the aircraft based there during the war. it is quite badly corroded, but after a quick wire brush, some numbers and letters are visible on top of the piston. was wondering if anyone knew if there are any ways to try identify said piece? best regards. s.:D
