I recently shipped a '66, and the handle was broken in transit...lesson learned, they remove easily enough (while complete) to remove them before shipping.
The purchaser got his replacement in Edmonton (western). You can also find them on fleabay, and a few other places too...(Epps, ad in the EE, numrich (sub 20$ part with 25$ "dealing with Canada fee")
For the interim, you can drill a small hole in it's stub, and use a screw for a charging handle.
Nifty rifles.
