Did you notice that it looks like all the parts have been painted grey and rubbed as to show wear.
About 15 years ago I had an opportunity to get a VERY nice Prussian Off Arty for $650 off of e-bay . I already had a wartime Off Arty with the chinscales 50-50 zinc and brass with the silk missing in the liner.
I put it up for sale on ebay and 2 newbies went at it driving the price up to $750 . That financed my upgrade plus I made $100 on the deal !!!
