Wanted: Flight suit

Well not sure where to stick this so i guess heres best. But im in search of a mark 14 RAF flight suit (or similar) my coveralls are ok for getting under aircraft but the more things i go flying in the more i need something more practicle as the coveralls are baggy.

Ive done some googling and seen 1 or two sites with what i want and have sent of emails but most dont have what i want.
Ive also been though ebay

I was wondering if anyone had one that they dont want any more (depening on size) or know anywhere else that stocks them.

The suit i want must have kneeboards

Hope someone can help

thanks
