How about refinishing the wood of k31,k11 ? There is no wartime history in them. We are restoring old cars to look new.
I have seen many different finishes on the K31 & K11's. The K31 can be shiny or not. It depends on the wood too. Walnut takes a finish better than Beechwood.
Try tung and linseed oil with a bit of lemon oil (thins the mix).
