That is a beautiful pair of guns but I think the price is 10K euro more than they are worth. Only way to know is to buy them and then try to sell them later. That is one way to find out for certain that you paid too much.
Classic use of straight grained wood. For 45,000 USD most here would expect much higher level of figure in the wood. Funny how little some people are concerned with great wood, perfect checkering or extensive engraving with inlays. Beauty is in the eye of the beholder.
As to speed of use, many Corvettes are not driven much over the speed limit and the 55+ year old owners still enjoy them. I would still enjoy them if they were slow to load and I could only enjoy them S-L-O-W-L-Y.
