Manxman. 1ST , I hate hearing the word deactivated.... but I do understand.
it's a personal taste I guess.
I own a 4 inch = 1918, 6 inch (navy)1920 commercial , & a 8 inch (art.) 1916 dated. I never sought these out, they all came to me at different times.

some don't want third reich at all , others that's all they want.
Can not comment on deactive prices myself .
most seem over priced in general, plus some sellers do not account for all original parts, or do not account for the overall original condition.
just a luger , price it high. jeff
