If you have a Truth Window Hardware Handle stamped or cast 45054, they you have the Truth Long Handle.  The number is just a number cast into the handle, so it does not tell us the color or anything else.  It just tells us it is a Truth Crank Handle with the 11/32″ spline (operator shaft size).   The only manufacturers that I know of who use this size shaft are Truth and Wright Manufacturing.  You can replace your Truth Long Handle with the same crank handle, or you can choose any of the Truth Handles on our Window Crank Handles page of our website.  This is may be helpful, especially if you have mini blinds or plantation shutters you are trying to work around.  We stock the Truth Long Window Handle in 6 different colors.   The image below shows the Truth Long Window Handle.

the above image shows the Truth Long Crank Handle and the measurements. This handle is shown in the gold color
