Yes Vette447 and quoting my favourite watchmaker "you never actually own a P.P, you merely look after it for the next generations" - or passionate hunters/collectors, as I have two daughters...

I am also inclined to agree with DarylS comment about Elmer firing left barrel first. His .476 seems to have a slightly more visible firing pin mark on left hammer compared to the right, his WR was also received with single trigger selector on “L”.
