Go ahead and build it for the group. As best we can tell, they were present in Korea during the hostilities, they just didn’t see any active combat there. So it still qualifies………….
The type did see combat with the French in Vietnam, a little while later.
I like the work you have posted on it so far. It looks good. You mentioned one of the things I don’t like about “rubber band” style one piece tracks, and that’s how to keep them together. I have successfully used a stapler in the past to keep them joined. It will work in a pinch.
These one piece tracks do have their good points though. They are much easier to build and you can have both tracks installed in minutes, versus a day or so of tedious work with the individual link sets. Do what works for you………….. It’s your model. Have fun and learn something while you are at it……….
