Someone took a Crescent .410 and upgraded it. Seller is trying to imply the upgrade is a custom gun. "This is a full custom Side by Side 410 Ga shotgun marked, Warren Ferguson- Birmingham. Mr Ferguson was a custom gun and stock maker, also a collector of many of the German guns we are and have been running."" While it might be a custom upgrade it is still a Crescent .410. Would tell the new owner what he has is a Crescent hardware gun that is a pig with lipstick or just keep your knowledge to yourself? It is at $2,625.00 right now. So a fair bit of coin.
