That is one cool bit of exotic Maico history Firko. I hope you do all of us a treat and put up a full photo spread of
detailed before pictures. Lets face it, doubt there would be another in Oz. Or too many anywhere for that matter. Exciting score.
This is the item I needed help with, it is currently globe trotting.
It was listed as a 1952 M200 tank, owes me AU$254, but will be worth it if the inside is as good as the outside.
It certainly looks right for a 1964 X3 360 and the smaller of the two that were used on the Pre-60 blizzards as well. Anyhow, I guess we will know soon enough if the mounting holes are an exact alignment on both frames. The computer screen images suggest a worhty gamble.
