I remember building a Hubley Model A when I was a kid. I'm not sure if it was 1/16 scale, but it was pretty large. It was kind of difficult to build because I had my right hand in a cast at the time, but I could use my fingers a bit. I recall it was a nice model; fairly good engine & drivetrain, but the metal parts needed a lot of cleanup. My cast wound up being sort of metal body colored instead of white. As I recall it came out OK but was a bit sparse on detail. As a kid I didn't care, but if I was going to build one today I'd try to detail it better.
I recently found some late 1970s Monogram 1/24 scale metal body kits that are pretty nice. They have very nice metal bodies & lots of nicely detailed plastic parts, typical of Monogram classic cars. One in particular, the Jaguar XK-120, is a real beauty. There are six different models in this series; they're great kits & will fit in well with all my other 1/24 cars.
I mentioned them because I think I heard at one time that Hubley contributed the metal body castings for these kits. Can anyone verify this?
