401/403 Rear window wood frame.

[Geoff Kingston]

I have seen a few good ideas over the years on how to replace the rear window wood frame on a 401 or 403, sadly I only had the foresight to buy one when they were readily available from Bristol Cars and while I still have it I now find myself in a position of needing three.
Is there anyone reproducing these or is anyone holding new old stock, I am too old , lazy and impatient now to follow some of the DIY solutions, though if push comes to shove I have an idea in mind which does not involve wood.
