FWIW, Weaver's E8 tooling has a "big" detailing error - they actually left off the exhaust stacks. I noticed this one day some years ago when I was comparing the Weaver E8's with the K-Line versions. "Wait...what's missing here?"
I have the NYC versions. Well made. Like tanks. Samhongsa, I think. They deserve command/sound/cruise, but I have never upgraded them.
