Just for the design aspect and that history. Not much would take the place of a 1911.
I was going through old negatives last weekend and came across some pix of my dad's WW-II ''bring back" P-38 on a German flag of the period. I will scan those soon. That Walther was the first handgun I ever shot, dad took me to the outdoor range across the road from our home when I was about 12 or 13 and was my first range instructor. Likely spoiled me for life where it comes to Walther arms. That P-38 was stolen some time in the late '70's, insurance company 'replaced' it with a NATO version, but that certainly wasn't the same.
As for the Accutron, I remember listening to the hum. A pal of my dad's had one of the early examples, it kinda bothered me that I couldn't open it up to see just what was going on in there.

BTW, I've got the info for an outfit in NYC that still does service and repair of them, they likely have the largest parts inventory in existence, too.
