Thanks Roger.

What a great website, it looks like my mate was nearly spot-on:) .

If the show I saw was in 1971 then the Spit would have been AB910, if it was 1972 then it would have been either PM651 or MH434. It’s a shame I can’t remember the exact year but I was very young at the time.

Thanks again.

Bob.

Assuming we are talking flying Spitfires at an Airshow here.

PM651 is a surviving but static Spitfire.

This looks like a ‘typo’ for the BBMF’s PM631.
