Thanks giove. It's exactly like all of the others I've seen, & probably one of the very early H&H conversions. The radius on the 'shoulders' either side of the front pad spigot is more generously rounded on the early conversions, & the pad screws being unstaked is also the norm from the ones I've seen, as is the waisted foresight protector. The sight protector will probably be marked SM 41 somewhere on it.

Thanks for sharing.
