Well i was handed a 1914 circa Colt Police Positive Special 32-20 today in about 70% condition as the mechanical condition is excellent but needs blueing,Just wondering the value and if i do have it reblued how much does it generaly cost to have a pistol  just hot blued?

In "About" 70% condition, the value would be "Around" $300 to $350.

Due to the hand labor and the EPA regulations, gun bluing has gotten expensive.

The going price starts around $125.00, and WAY to many of the people doing it are hacks that will over-polish the gun and ruin it.

GOOD gun re-finishers don't work cheap, and nothing looks worse than a fine old gun that some ham-handed polisher rounded off all the sharp edges and dished-out the holes.
So, you can have CHEAP, or you can have RIGHT.

Here's some places that offer re-bluing:

www.fordsguns.com/  (VERY GOOD)

www.apwcogan.com/Greetings.htm   (GREAT)

www.apwcogan.com/Greetings.htm   (About as cheap as you're going to find, but still be "OK', not great).

There are plenty of other places, do a Google search fro gun bluing or gun re-finishing.

Note that the few locals that still do bluing are typically hacks.  This is simply because they only fire up the tanks once in a while, and they don't develop the necessary polishing skills.

If I may?

I would send the gun back to Colt for refinishing. This way you will have the factory support behind the value & workmanship on the gun.

Agreed, send it back to Colt for the reblueing.
