Greetings folks and thank you for all suggestion and comments. Thank you tmg513, with my limited computer skills I will try to PM you. I have also passed on details of Douglas Valley breakers to the owner. Have also researched Holdenmorgan.com.uk and in a 2000 catalogue they list sidescreens. Also discovered they have a associated company dealing in aluminium extrusions and I understand at one time supplied the factory with the extrusion. Does anybody know whether they still do that knowing that they are no longer Morgan agents. Amazing information coming from TM members and again thank you all.
Doug
