Frank,
Having worked in the plastic injection molding field for about 3 yrs when I got out of the military, I can say that there are a few answers as to why your parts are off.
1st - the inserts that are put in the mold could be either cokeyed or not screwed in right. I have checked mine in the Rumanian kit and they are fine.
2nd - The inserts screws could be loose thus when the mold closes and the polypropylene is injected, they fill the part but then come together fully creating an off center part
3rd - and most likly the caus eof your dismay I am afraid (IMHO) is that someone did not clean the mold off properly, spray enough mold release, or a piece of sprue got stuck making the mold off center.
The only thing I can suggest is contacting Hasagawa and telling them that part of your pieces are buggered and you would like new ones. Personaly, I have never delt with Has, but Revel was very helpfull in sending my new parts.......it is worth a try mate!
