Thank you for showing your two pistols.
I remember 1985 like it was yesterday-even 1965---where did my life go?
Sorry-if you want or need a closer idea of prices for your Mauser Parabellums you can look on Gun Broker, search "Mauser Luger" like I just did and it turned up 220 listings, perhaps 10 are for Mauser Parabellums.
Of course you need to watch over time to see what shows up and what really sells.
Do you have all the other stuff...hang tags, test targets, manuals? That all adds to the value.
Best Wishes, Joe
