So i bought a Colt Double Diamond Officers 1911 for $1750,advertised as "nib" from a dealer.When i got the gun,the guns is new in the box[beautifull] but the serial number on the box is 0337DD instead of 003xdDD on the gun.Contacted the dealer and he said the boxes got mixed up somewhere down the line and he had no way of knowing where the original was sent.He offered to send me a period correct box with a blank tag or refund my money and take the gun back.My question is should i keep the gun or send it back?My second question is how would a run of 150 of this gun have a box tag with 0337DD instead of stopping at 0150DD anyway?Could be the box was part of a two gun set of 1000 that came with a Double Diamond Python?Help me out Colt gurus and collectors.
