Smith barrel threads

[matts]

i Was able to win an auction for a used Smith 327 pug nose tonight and since I’ve already got one I want to make this one special. I would like to have this rebarrelled and was contemplating trying to find a take off barrel and that brought up the question of smith barrel threads. Will any smiths barrels interchange or does an n frame have to go on another n frame?

Thanks

N's go on N's. Not sure if the alloy frames have the same threads as the steel frames.
