Rangefinder specs?

Anybody have the dimensions of the ROTJ rangefinder? I going to try my hand at making my own and creating a mold for a resin piece.

I thought wizardofflight did one, but then again he dose so many drawings I could be wrong. But, diffrent helmets have diffrent size RF's, BM RF's are a diffrent size then lets say a DP RF.

Thats true Pogo.

Can somebody with a DP give me some rough measurements of theirs?

Thanks guys
