I'm not familiar with that window, unfortunately. Your best bet is to check the size of the spline. The 39-195's hole diameter is 7/16". What is the hole diameter for your old handle?
A quick learner from Coloroado says:
The hole diameter of the old handle is 11/16".

I'm looking to replace this handle with a T-crank handle. Do you know which T-crank handle will fit.
A quick learner from Colorado says:
the hole diameter for old handle is 11/32. What T-crank would work to replace this handle?

Tom from SWISCO responded:
I'm sorry, can you confirm the diameter? I'm not sure if it's 11/16" or 11/32". We don't have anything in 11/16", but our 39-102 is 11/32".
