Paul from SWISCO responded:
I'm afraid I don't know what you have based on this information alone. It could be something like our 39-031 or 39-032, but there are too many other possibilities to be sure. Please show me a picture of your operator fully removed from the window and tell me its dimensions. That is the only way we can confidently offer a replacement.
A home owner says:
I dont know how to send a picture except to send it to another phone I am handy just not techy lol I guess I could order both window cranks to see if one fits I just need the cranks the house I bought has only one crank thank you

Paul from SWISCO responded:
If you can't send pictures, just carefully examine the pictures on our 39-031 and 39-032 store pages. We list detailed dimensions. See if they match your current hardware. Also keep in mind that the 39-031 and 39-032 are the same, just for different sides.
A handy person says:
my daughter came home and helped me post pictures hope this helps thanks for your patience

Looks like you have the old Bilt-Best operator, which I'm afraid is no longer available. You will need to retrofit either our 39-027E or 39-013 operator, depending on your arm length. You will also need a new track like our 39-505 and a new handle, such as our 39-114L. You will most likely have to cut your existing "sill cover" to fit the newer style operators. You could consider having a carpenter or contractor to make a new sill cover. What do you think of this solution?
A quick learner says:

I see, I'm sorry for the confusion. The term "crank" is generally used to describe the whole operator unit. It sounds like you just want the "handle." What is the size of the spline; that is, the hole that fits over the operator? The 39-114L spline is 11/32", for example.

i have no clue what size it is I was hoping you would know from the pictures and number on the handle if I need to measure something let me know

Tom from SWISCO responded:
Yes, we need you to measure the spline. This is the hole in the handle. I posted a picture of what the spline looks like on our 39-114L as an example. Please measure this and let me know what it is.
A quick learner says:
the hole measures 5/16

Dave from SWISCO responded:
Thanks. If you say your spline hole in the handle is 5/16", then our 39-274 handle may work. But make triple check to make sure it is 5/16". The size of a spline can get pretty specific, going even into the 1/32" range.
