Cheers Andy,
As Ringo Starr would say, "Please excuse the lateness of my reply". I was in process of downloading a really interesting and complete manual for repair/maintenance of 40mm Bofors Gun. Finally got it finished at 0130hrs. I would highly recommend this site:
http://www.hnsa.org/doc/index.htm for anyone interested in a range of military manuals, mostly naval, but not all. Some interesting photos of refloating the USS Missouri in 1950s. I didn't even know it had been grounded until I saw this website.

I have downloaded the convoy light photos. Here they are!

This is a photo of a Canadian convoy light I saved some time ago. It looks the same to me! Bracket would be easy to replace.
I have written to Dean a little while ago, to thank him for the window frames. I mentioned the first one I started on, a few days ago. That one was disappointing and would require a great deal of remedial work. The second one on the other hand, was an entirely different story, I am pleased to say

I will write more about that in next posting. I took photos to post too.
