Hi John,
Thanks for the rapid reply, a scan of the drawing will be much appreciated, to help sort out the dimensions of the firebox.
This will be my first go at this sort of scratch aid kit, I'm a fairly experienced kit builder, but have not yet tried anything that requires this much scratch building of details. This might be one to document as I go, (Might not be for a while though - I'll have to clear the workbench first!).
Cheers
Jeremy
