Northern modes had no instructions - well nothing useful at all.thank you David, yep you jigged my memory about the terrier.
detail etc you had to photograph the prototype and find detail bits.
Mechs - well the Y probally SEM black beetles if available The W could use a Terrier doner or a thomad the tank doner.
I have a copy of the Northern Models instructions for the Y-class, and one page of the T-class instructions. I dug them out of my shed, so they're a bit water damaged - they date back to 1992! Theyre really just typed sheets, with some prototype info on one page, some assembly instructions on another and an outline diagram from VR on a third. Are you still after them?
