I let go a 7 X 57 set-trigger pre-war Oberndorf Mauser sporter that a Canadian regimental sergeant-major "liberated" from a German baron's assets on the Dutch-German border and traded to the regimental chaplain who brought it home to Nova Scotia. It broke my heart when a really good gunsmith drilling for a scope mount had a really bad day. A perfect rifle of craftsmanship, utility, precision of the highest order was no longer a perfect rifle for me. I let it go and wouldn't want it back. There's a hole in it that shouldn't be there.
