This is actually the Dragon/DML kit. (Most of Dragon's 48th kits were produced from slightly retooled Trimaster molds.) I haven't built any of mine yet so I can't tell you how they fit and all that. But even though it's approaching 20 years old, this is the most accurate kit of the Me 163 as of today.
Here's a couple reviews:
