I just ran across a nice example of a Flues Model in 20-gauge. Very good weight (5 3/4 lbs) and dimensions (14 1/4 LOP to the plate, 28-tubes), it even has some very attractive light engraving. I've just not seen many 20s, and most (if not all) that I have run across have been badly used-up. The price tag seemed shockingly inexpensive. Is there something about the Flues guns that I don't know about? I would assume that because of it's rather petite nature, that lower pressure/lower velocity shells would be good policy. Is there something else?
This brand consistently delivers very good quality for price paid. I have seen knockabout grade 20ga extractor gun marked New Ithaca Double. It had good wood, nicely finished rib, wood checkering and matting on top of action to prevent glare. The price was well under $1000. No other classic American small-bore can come close in quality to price to that offering. Enjoy your new treasure.
