I'm getting caught up after a couple days on the road. Keith, I saw your email and will respond tomorrow. As for me, I'm exactly like Fabian. I simply don't trade. I purchase. I'm patient and have the vast majority of the common weapons and have been patient for years regarding the rest. I'm also very disciplined when it comes to buying and NOT trading I'll sell everything slowly over time when I'm semi-retired, but never expect to find EVERYTHING that I would like to have to fill gaps in the Collection. And besides, IF I ever managed to find everything, it would take all the fun out of the hunt!
As for pricing, when it's a one of a kind or once in a lifetime, you have to go with your gut feel and how much disposable income you have at the time. If you are a trader, then you have to estimate what your trading stock is worth and count that as disposable income. Based on my own level of interest, if I were flush with cash, I would go as high as $3K U.S. for a very good+ "Bronze" Comblain. Some folks would probably go higher while some would say that was too much. It gets to be quite personal with most collectors for particular rifles or bayonets.
Just my $ .02 worth. Beautiful rifle Fabian!
