Steven,
I finally got home and managed to check out my Goodall MK2/3 A class plans.
I have 14 x A3 sheets and one A1 sheet.
The A1 sheet has the rudder profile as well at all the bulkhead shapes and bow spacers.
Are you only missing the A1 sheet.
Email me at phillbrander@bigpond.com with what you are missing and your postal address and I'll get it copied later this week and pop it in the post.
Regards,
Phill

I know that the voices in my head aint real,
but they have some pretty good ideas.
There is no such thing as a quick fix and I've never had free lunch!
