ww11 period 36' pattern flying boots

Had these 20 plus years, tried to research them, would love to know history, can anyone help?
They are genuine 36′ pattern issue boots, NOT private purchase-Raf ‘style’, or repro 36′ pattern. very ‘tired’, soles replaced which is not uncommon. heels poss original, or early replacements?
was told service-758717 or 738717 number (faint) on inner pullers is RAFVR, ‘HB’ also on inner pullers which are fully AcrownM stamped, with 1937 date code. I think the small, crude stick figure was meant to be the Charteris, ‘Saint’?[ATTACH=CONFIG]233274[/ATTACH][ATTACH=CONFIG]233275[/ATTACH][ATTACH=CONFIG]233276[/ATTACH]
