The Legend kit is just a shell, nice detail, but mine is too short. The vehicles are built on the long hull, so some creative stretching is needed. Unfortunately, resin shrinks, and all too often, allowance is not made for it in the master.
Be nice on the MP Models M50. :-) It is actually from 1988, and it was only two of us. Until Tasca, it was the most accurate M4A4 around. Believe it or not, it was done solely from photographs from the Budge collection, not actually having seen an M50 in the "flesh" until 1992. I would actually recommend using it over the Dragon kit:
1. MP kit, for upper/lower hull.
2. Tank Workshop conversion set.
3. Tasca suspension and tracks
4. Formations or DEF Models turret
5. Aber photoetch if you care for that
If costs are a factor, one could just use the MP kit, but correct the gunner's sight to earlier flat style; cut down the center portion of the weather strip on top of the forward extension and replace the jerrican holders; do some AMS detailing and it will turn out fine. There were M50s with HVSS and the 3-pc nose.
