Thanks G. I decided to go ahead and use the remnants of plastic turret ERA I had in the stash, got mostly done, and realized I would be short a few pieces, so in a huff I pulled out the box of Verlinden stuff, took a look at it and realized it was good stuff, so off I went. Prepping it is not bad, just gotta watch the dust, and I'm happy enough with it I'm going to replace all the plastic blocks with Verlinedn resin, if I have enough... er, I'm glad I have two sets of the stuff, since a lot of the pieces are chipped and broken, probably from lots of handling. This stuff is old.
So, right side, the back three blocks are Verlinden, the rest plastic, both ESCI and Academy:

And the left side, only the front three pieces being plastic, the rest Verlinden:

Only problem: I have a burst blister on the end of my right index finger from holding those blocks as I sand a good millimeter of plug off the back of each one, kind of like the blisters my wife gets when she picks her guitar up after a few weeks and plays for an hour or so.
