Large Scale Parts Tree Identification

[Tom Geiger]

Hey folks! I don’t know a darn thing about large scale. I came into these three trees in a big parts hoard. Can anyone ID these for me?

The bottom Sprue looks like it came from Monogram's Big Deuce, the top of the firewall and Pontiac valve cover are kind of a giveaway. The top looks like something Aurora while the middle looks like Lindberg, probably wrong on both!

Top two are from one of the various versions of the Lindberg T.
