Then, not a Colt at all but an 1858.
Snubs tho..are fun 
This one i fabbed myself from an original, and before you throw a fit.. LOL, the gun was ruined by British law before i bought it. Brit law seems to have changed over the yrs, and this one i bought as "deactivated" with the sole intent of building myself a snub out of an original - as that´s the one permit exempt to us.
Len on here provided the stock material which is REALLY old black oak, i´ll let Len fill that part in if he reads this.
About the grips' material:
It's so called sea drenched oak, aka Black oak. Oak would perish in salt water due to a certain type of worm, but in bracken water it turns black over a period of 100 to 200 yrs and becomes rather sought after and expensive, used for artefacts and designed stuff. This specimen comes from a rib of the Swedish galley HMS Compass, sunk by the Russians in AD 1723 in shallow waters in the archipelago. I've got part of a rib with copper nails still in it, on my wall.
