PPK;

That seems to be a very good price for a 147E.

I offer a bit of comment for you. Some 147's have very small firing pin diameters and consequently a small diameter thru hole in the face of the action. While others have larger thru holes and some even have the much desired removable "striker discs" in the face of the action. Desirable for the double rifle builder.

Higher pressure double gun cartridges require firing pin and thru hole diameters appropriately sized.

You have there in Canada and maybe next door to you the extremely valuable knowledge, wisdom, skill and experience of an excellent and renown double rifle builder--Ron Vella who is a member of this board, who I am certain invites novices into his shop.

Good luck.
