converting dao revolver to double action?

[coopershooter]

j&g sales has used police revolvers that have no hammer spurs.  Can a gunsmith put a replacement hammer in one?
  thanks!

I believe there is more to them than a missing hammer spur.  They are internally modified to fire double action only.   They could possibly be converted back, but I doubt it would be worth the expense.

If it is a standard model I would think so.Most are pretty easy to open up and do the change. What is the model.

[coopershooter]

They have model 15,s 64,s 67,s     All are around $250.

Having worked on Smiths for the last 35 years, I can't imagine that being a big change or an expensive one. K frame hammers are abundant.

Thank you!
  I Have a model 67 4 in.  I Like it so much, I,d like two!  Well maybe for one of my boys. :-)

May have to do a hammer and trigger, but I suspect the doa is nothing more than the cocking notch eliminated.

My guess is they simply bobbed the hammer.
Pull the trigger a little to get the hammer moving and then use your other hand to set the hammer taking your finger off the trigger.
If the hammer sets.  Then it is simply a bobbed hammer.
If it does not set it is a DAO and as Dee said, replaceing the the hammer and the trigger will simply be replaced.
and ta da.  DA/ SA revolver.
Other than that just use it as a DAO till you get the parts.
