It don't look like it was stored 60 years in the holster...
"This...has been in our family since it was brought home tucked in the bottom of a duffel bag at the end of the war in Europe. This pistol was cleaned and lubricated, put away in its holster, and has never been played with or fired in all that time."
Never??? Never ever???
BTW: Is that tongue & buckle holster strap normal for a WW II Luger holster??? And if it's been stored for 60 years...why does it look so worn???
