I recently picked up a 1947 made A-5 with the knob stock. It had been cut and fitted with a Jostam Anti-Flinch recoil pad which is rock hard. To replace it, I understand I'll need to fit a pad to my stock, but at least one pad I have is a somewhat different profile (slightly narrower) so I'd have to go to a larger one with more grinding to fit. Can anyone suggest a close fit pad for this stock to minimize my fitting?
