To add to this guns rarity, it has iron (not brass) triggerguard and grip straps. The reason for this can be found on page 44 in "Colonel Colt London" by Joseph G. Rosa. "So far, all Colt's revolvers had been fitted with brass straps and guards, and Alvord's contract with same was for the manufacture of these parts at a fixed rate. Now the matter of mountings was in question. As most collectors are aware, there was a gradual change in production techniques in the London made pistols, especially with brass giving way to iron for guards and straps. The English did not like brass as it looked cheap and had a military association. Alvord had no contract for anything but for brass and could not easily switch to iron." The Book of Colt firearms" by R.L. Wilson comments "several hundred model 1860 revolvers were sold through Colt's London agency, a rare variation is the army with the London barrel address. These were marked specially for sale in England, and are usually found in the 158000, 167,000 and 168,000 serial ranges, backstraps and triggerguards are blued steel. All were manufactured and finished in Hartford." The previous owner who purchased the gun as lot 2074 from Butterfield noted at the time, "condition is overall smooth clean gray metal, cylinder scene is very good, grips retain 95% finish. Not the condition that I normally accept but this is the First London bbl address that I have seen for sale in 15 years."
