You can find mudgards by the firm called "Vintage steel". They have both front and rear of the right modell but shipping is expensive because they are in Autstralia.
There are actually a lot of differences between the early KM20 and WM20 model. The Deluxe version was only applied pre war (1939) not post war. It is easier if you can give the year of manufacture of your M20.
The Deluxe version did have a panel tank with the instruments. These tanks and instruments are difficult to find nowadays, replica tanks are available from India but I won't buy those. I have such an original tank with the instruments (not for sale) and can send photo's.
