do you know if they still produced the three screw gun until parts where used up?

What would be the likely year of manufacture for this gun? Super Black Number 80-62642?


Sorry, I guess I have tree seperate question.


Thanks for any replies.


Bob

I believe the NMs came out in 1973.

'73, as noted.
Denis

Late 1973 . . . one of the last Old Model Supers.

Thank you for the replies.

Does any one know about the three screw question?

Unlikely.

Many three screw parts were used on the Old Army, which was produced until 2008 or so.

Yes, for a while, they produced 3-screw actions in the New-Model frames. All 4 of mine date to the early 1970's time frame.

How did they (Ruger) do that (produced 3-screw actions in the New-Model frames.)?

Thanks,

I'd be interested to see any New Model frames and serial numbers carrying Old Model internals, or any New Model frames carrying Old Model serial numbers.

O.K. I know the .357 Magnum went to a large frame, but otherwise, how do you determine a gun, .41, .44, or .45, is a Three Screw made on a New Model frame? What is the tell-tale difference? This is something I've never heard of before.

Nope.... once Ruger switched over to the New Model in a particular series, they didn't keep producing Old Models.
The NM Super Single-Six was first and once production started, Ruger did not produce more Old Models. Then the NM Blackhawks and the NM Super Blackhawk were next.
One thing I hadn't thought about till your question came up however is how the cylinder frame castings themselves might be different between Old Model and New Model...I'm thinking they have to be different for some of the internals but not sure on that.

I am curious ~ how do you differentiate the three screw New Model frames from the older ones?

Bob Wright

Ok, I might have misspoken - I have 4 Blackhawk Old Models with sight ears (not flattops) that are 3-screw actions. In my day, the change from flattop to sight "bumps" were referred to as "new models"

New Models use Ruger's transfer bar ignition system, and only have two cross-pins thru the frame. The frames are roll-marked "Ruger New Model".

The pre-73 guns using the original "three screw" mechanism are the ones usually referred to as Old Models. These consist of both the original Flattops and the post-62 "protected rear sight" types.

The last of the Old Models and the first of the New Models were manufactured in 1973.
