This is a phot of two Colt DA New Army/Navy Model revolvers. Both have a pushbutton that locks the hammer. The second one has a push bar cut into the rear gripstrap that does the same job as the button (which is disconnected). The parts are numbered and the grip has been cut away for viewing on the one with the safety bar on the grip strap. I was initially thinking maybe a toolroom gun??? Anyone seen anything like this on any other kind of revolver or on any other Colts? Bob Best

I've never seen anything like that before. Locks the hammer? Why, do you think? To what end?

What is a toolroom gun?

Thanks!

Hi Onomea,

The buttons work like a safety device... (The key lock of 100 years ago)... you push the big button in to set it (lock the hammer) the small button at the bottom of the big button protrudes. This releases the mechanism when you push it in. On the nickel gun, the grip bar takes the place of the small button that releases the mechanism. By squeezing it the "safety is released and the revolver will function. This may have been an idea for a safety device for the British or European market ... they used safeties on revolvers there...

A toolroom (or experimental prototype) gun is one that is used to make modifications in the Research and Developement department. Sometimes the modifications see "daylight" in a new variation that is marketed and other times the idea is discarded...

Some collectors/writers have postulated the Colt used the small square to designate a experimental prototype or toolroom gun. I personally believe that the small square was used for a new material or machining process rather than to designate a prototype or toolroom gun.

I have one of the original protoype revolvers of the Colt Model 1889 New Navy that was developed by C. J. Ehbets... (See page 322 in the Book of Colt Firearms, or page 7 in my book). It does not have any squares on it at all... Hope that answers your question... Bob Best

Hi Onomea,

Here is another toolroom gun that I have. This one is a cutaway that has an additional sliding metal tab fixed to the cylinder release thumb piece. There is a notch milled into the left side of the frame to allow it to lock the cylinder release to the rear... Why, I don't know.... Any comments or ideas are welcome!

No of these guns appeared in my book as I had reached the maximun space limitations set by the publishers... Guess they will have to go into volume 2! :) .... Bob
