This is the most difficult parts assembly I have ever made:
If you don't immediately sense how difficult this is, just try it sometime; try cutting out two bowls which will fit together to form a perfect, symmetrical ball with only one third of their edges to butt/attach them together. Oiy! Of course, this could all be done very easily if the turret were also being attached to a flat base (ring) - and there is one provided in the kit. But I couldn't use it (yet) because I need to use this as an armature over which to form a truly clear part; to replace the dirty-brown tinted plastic of these MPM parts.
Yes, I'm again going over to Don Czech's and we gonna make up a mess o' more awesome stretched thermoplastic clear parts!
But first I needed to do something extra to prepare these particular parts:

After the above, the resin "freezes" in place to form what can only be described as "parts popsicles":

The inermost layer of clay remains embedded in the epoxy wherever it intruded through a surface piercing, leaving some flecks of blue inside the part-sicles after the piercing is dug out, but the appearance of the insides isn't important. It is the outside surfaces - including a surprising degree of their textures - which the thermoplastic will pick up, when stretched tightly over these armatures. So, stay tuned for that.
OK, by now I've recovered from the initial trauma sufficient to back up and tell you about this build:
But back to the MPM kit - of which you will see much more later: you may perhaps already surmise from the above example of the clear parts that it is rather crude; having also thick parts - with particularly thick sprue attachments - and no locator pins/sockets on key pieces, such as the fuselage halves, as well as having sparse and rather crude surface detail. It attempts to compensate - and we shall see how successfully or not - by including some nice-looking photo-etched details, among which is even a little black anodized fret containing one of the most effective - and apparently easily installed - depictions of an instrument panels I've ever seen! A very interesting mixture - and concept - for rounding out such a kit.
In addition of course, the subject itself - the Tupolev SB-3 - is an exceedingly rare one. I have been looking to build this plane since I was 13 years old, but had never seen one anywhere. This MPM kit was one of several I bought in October at the St. Petersburg PeliCon'07 show (Thank You, Earl!); after only learning of their very existence for the first time when I ran across them in the vendors' stacks up there.
In any case, with the above turret assembly and preparation of the other clear parts for duplication, the build of the Tupolev SB-3 is now officially off and running! (Progress updates to appear as "responses", below.)
Cheers,
