Can't help you with current pricing, sorry, I will, however, make a point about "value".. the way I see it, the guns aren't increasing in value, but are going up in price.
Part of that has to do with the buying power of the dollar, and part of it is "get it now" idea, and how everything out of production is somehow "collectable"...
Last Hi Power I bought was Belgian made, commercial gun, very well done and cost me $300 however, that was about 40 years ago...
$1900 is, to me, barking stupid, UNLESS you ARE a collector, with a fat wallet and it fills a niche you need filled.
And, even then I think its too much..
You can get a functional HP in good shape for around $700 + these days, how much more you want to pay depends on you. Brownings have always been expensive guns, the work is high quality and the finish is excellent. A weeks pay for an average middle class worker seems about right. How much that is in $ depends on what time period you're looking at. Right now, prices being asked are stupidly high, and will only get higher, over time IF people pay them...
Good luck. If you want a good quality, Hi Power pattern gun, the Springfield SA 35 is the best I've seen. If only a Browning (FN made) fits your wants, expect to pay top $. Good Luck
