[ARC5] BC-458 and 696 parts question..

[hwhall at compuserve.com]

Mike's scan shows 3 inches long dimension for the plastic bit. Mine measures 2 & 13/16 inches.  I note that the window in the metal part is slightly wider than this, leaving a narrow air gap at either end. Distance between the outer hashmarks on the plastic are 2 & 7/16 inches.
 Perhaps mine has undergone some shrinkage in dimensions?

 Hi Craig,
 
 You can get a higher resolution copy of the scan I sent you, along with additional info,  by going to the web page - https://aafradio.org/garajmahal/Command_set_roller_windows.html 
 
 If you can wait, I'll try to get around to putting the other dimensions on the image in the next couple of days.

Wayne: Mike has given me a good start from one he has. I need to print off the file and play with the sizing to get the dimensions correct and then make a set of drawings and have him match them with the window. I need to get some mylar to print on so that I'm working with a stable copy first.

Has Mike Hanz already given you all you wish or should I still pursue getting some pics?

 Attached is a flat bed scanned negative of the window, Craig.  I think 
 you can scale the other measurements from it.
