Hey Chicken bros,
long time no see.
Look at that, yet another piece from a known donor, this time our beloved Ferrari 312B.
Sometime last year, I was looking at that outline on the back of the Chicken's head and thought that "something was there"...and opened the 312B since that outline "kinda looked like those shiny angular parts". However, I must have glanced rather lazily over the J sprue, threw it back in, and life went on.
A few days ago, on the never-ending quest to find the 'inner thigh plate' and the main gun barrel bracket ('double headlight bezel'-looking part), I was browsing the Chicken ref folder again, and The Force pulled me toward the 312B box again...and there it was....part J10.
Now, J9 is technically also a possibility, but:
a) the thicker segment on J9 is longer than on J10, and it "invades/disturbs" the dome area on the KV hull
b) it has 3 small locator holes that are not very appealing (unless they got covered with other part(s))
c) J10 with its "step" is more interesting.
So I'm placing my bet that JEJ used J10.
In both cases, though, the crude, molded-on chain of the KV hull is now for the most part out of sight.
Note that the faded outline on the right box is a degree or two askew counter-clockwise, possibly a result of quick re-gluing.
In all, a nice, functionally reasonable (vent/exhaust/intake) addition that adds more angularity and depth to the back of the head.
