Historical WAD Schematic Diagrams

[Matthew Snell]

Hi All

It's a generous offer Greg!

Richard has suggested that there are difficulties here - the gradual evolution of the designs in particular not being an easy one to cover! I also think "mining" the forum can be part of the fun. Caveats aside, I'm positive about the idea though and will be in touch privately to discuss.

I've now discussed my suggestion on the telephone with Matthew and he has agreed that I can proceed with this and see how I get on. The first thing will be to compile a comprehensive list of all the kits WAD and WD produced. I will do my best at this in the next couple of days and then publish for members perusal, comments and additions where there are gaps in my knowledge. Once we are satisfied we have as complete a list as possible, I'll proceed to the next stage of collating the instruction information. Watch this space.

[Greg.]

Apologies for the delay in completing the kit list. I have not forgotten. I've just got a lot on at present. It will get done

[Greg.]

Hmm, recognise what John has said in the News section about forum problems, but it seems all last night posts have disappeared.

So, consequently now not in context, many thanks to Alistair for forwarding several instruction files to me today.

Kit list will be up by the end of the weekend, subject to the website behaving itself.
