That messing with PE parts has got to be one of the classic definitions of insanity!
I bought, from eBay, a panzer 140/1, made by VM Co. Ltd. (I asked about that maker a year ago or so) and it came with more aftermarket PE parts than the model has original parts!
Not kidding either. I get three sets of aftermarket wheels, two sets of treads, aluminum barrel, enough PE to make three complete turrets (plus the original plastic one) full interior set, countless buckles, latches and other incredibly tiny details.
The sad part about the whole thing is the original kit, upon a closer examination, isn’t very good. The parts have very soft details, and the fit is iffy.
And of course the PE bits are supposed to help, assuming one could figure out the **^%*^%ing instructions that are written in either Polish, Czech, or hieroglyphics!
I’m sorely tempted to ship this entire set off to Biffa or somebody equally skilled, and have them build it for me.
