While my personal preference for Passion Wagon would be without this fillet for variety, it's conceivable that both configurations are correct if this airframe was still in service after the fixit kit became available.
I actually feel the same way you do, chunks. As I said in my very first post in this forum, unless the real plane flew in the war with the fin installed later on, I don't feel like investing $120 on a repaint. So actually I'm glad you found that site that has a pic of PW with the fin installed.
If I may nitpick one more time, two additional swastikas have to be placed underneath the first two in order for this plane to be accurate.
Don't mean to be a rivet counter, but at $100 a pop, these repaints have to be at least historically accurate. Just have that ME-262 kill in there and I'm sold.
With that said though, I really wish this release would take off so as to increase our chances of seeing new molds in the future.
EDIT: Now I'm confused. According to this site (
