I'm passing this info on to you from Chris Miller. He has the info that you need but your e-mail account is rejecting his e-mails. He's precluded from posting here right now because he has some sort of account problem here on HKN.
He has the 1/48th Revell kits of the Wessex, both the Has.3 and the Hu.5., boxed with instructions and decals.
If you can get your e-mail account to accept his e-mails, he can scan whatever you need and send it to you. Failing that I can act as an intermediary.
I will send you an e-mail myself to see if it gets through.
