401/3 door card

[peterg]

Has anyone experience of remanufacturing the door cards for the 401/3?

My plywood has delaminated and disintegrated. I am thinking of replacing it with 3mm marine ply and reusing the other bits from the old card as they seem to be in good condition.

My anxiety is how the card is built up and when it needs to be lined with leather before other parts, principally the door pocket and top panel, can be added.

Progress is slow but still forward!
