The ultimate custom rod? I fell in love with this car as soon as I saw it. Still one of the most radical custom cars ever IMHO. If this is ever produced in 1:25, I'll buy it.
I guessed that it was from the late 50's or early 60's, so I searched fiberglass cars by year starting with 1957 and when I got to 59, there it was. Not identical but very close. After that a more detailed search using Shamrock cars and BINGO.
No. Mold lines are usually thin raised lines on the parts where the 2 halves of the mold split when they remove the parts from the mold. These mold lines are usually found along the top edges of the fenders and the edges of the roofline. You can normally see that they shouldn't be there. Sanding sticks are usually enough to knock them down. If you look at the top of your seats where they were attached to the sprue, you will see a fine raised line running from that point down either side of the seats. Those are mold lines.
