This KdF-Wagen key I found after 15 or so years of hunting for it in Europe. Lucky to get it as they are Incredibly scarce and never had a chance at another one. Around 1945 the key cut profile and tumblers were flipped over (like a mirror image) and stayed that way moving forward. From what I understand the power on dash switch, drivers door handle, trunk and engine lid handle were all keyed alike. Most KdF-wagen beetles that survived were updated to 1946 era tumblers and keys soon after.
