Guys,
I was perusing the local classifeds rag and came across a for sale ad for a "1940's Wiesel (their spelling, not mine) Military Track Vehicle". The ad goes on to say that it has a newer Ford 6 cylinder with automatic transmission. Runs and drives. $1,500.
I don't know if that's a good price or not, and I don't know what affect the modern drive train has on the value, but I thought someone may be interested. The fella's phone number is 608-323-3871, which is somewhere near Arcadia in Southern Wisconsin.
