I believe that Bagheera windscreens are no longer available from the usual suppliers...

By usual suppliers I presume you mean Simon, Carjoy, HB Pieces? Here in the U.K. we have a glass specialist that deals with unusual cars and often has Bagheera and Murena windscreens in stock, and at very reasonable prices (like under £200)
We have just been informed they have 15 Bagheera screens in stock that they would like to move on now as they need the space. So they are prepared to offer a discount on the usual price. They didn't say but I believe they are probably Series II screens. I have emailed to check and also to see if they are tinted as I suspect.
If you need a screen you can contact Martin at UROglass, Bromsgrove, B60 3DX England Tel. +44 (0)1527 577477
