casement window operator on an entrance door

I have to reproduce a 1 3/4" thick door that has an operating casement window in top section of the door.I am trying to find an operator for the casement window and I believe you may be able to help me. I have pictures of the old door and drawings of the replacement door I want to make. I have already told the person I can make this but cant seem to find the proper hardware. PLEASE HELP! the problem is the door is 1 3/4" thick and the sash is 1" thick because we also have to put a screen on the inside of the sash. The crank has to be narrow in depth also as not to protrude to far past the face of the door on the inside of the house. Like I said I have pictures and drawings that I can send you. THANK YOU Bill

Enclosed is a drawing of a door we have to make with an operable casement sash opening with a crank. I was speaking to a gentlemen who asked me to forward this drawing and he will try to help me out. The sash only has to open 3" or so to vent steam from a bathroom. However, the handle can not be what is drawn. It has to be a handle similar to 39-108 white. I also enclosed picture of original door. Thank you. Bill Kane
