Well i had a bit of a clean up today and remember picking this up from a airfield dump.The thing is never cleaned it and it very nearly got binned.However i gave it a bit of a scrub and found some serial no.s on it.The inspection stamp i think is TAN 220 the other number reads 2-J98343 now it could have had a digit before the 2? also im not absolutly sure thats a J either.any help chaps?
TA215 to TA249 Mosquito possibly.
Oh one other thing - does anyone know what the part is?

Where are all of the aircraft buffs?

I have to admit the myriad British aircraft part numbering systems are a dark art I have yet to fathom, let alone master, but from my notes the "98" in 2-J98xxxxx indicates a Mosquito part, the "J" prefix indicating it is associated with the tail unit assembly.

All the best,
