WTB Ruger Old Model Three Screw Blackhawk trigger and hammer assemblies

I want to buy Ruger Old
Model Three Screw Blackhawk trigger and hammer assemblies to replace Ruger
transfer bar conversion parts back to factory original. I am looking for
several sets, just bought a few guns that have been converted and want to
un-convert them. I do not like the feel of the trigger with the transfer bar
assembly, it just don't feel right! And I am smart enough to have an empty chamber
under the hammer.

Thank you,
TRK
