It's one of those birds that will need to find a specific owner if you want top dollar. I could see it fetching decent coin at auction, but would be a hard sell on here. The rarity should bring some value, but the ugliness detracts significantly lol. New ones go for $750+ which is pretty steep, I've picked up lightly used field/speed for $350 fairly recently.
If you need to get rid of it, $500+$600 might sell on here, otherwise hold onto it for a few decades and it might come back in style...
Possibly the ugliest gun I've ever seen lol.
