Drawings
If you want to build a 1934 Nimbus in
original condition from scratch, it will be inevitable that some
parts cannot be found or that other parts are in such a deplorable
condition that they cannot be used, so that you will be forced to
replicate them.
Please find below drawings of some parts
that are often missing in a 1934 project.
I hope they will be useful for you.
