Maybe there are more than one version of the '61 catalog??
I don't have copies of the '60 or '61 catalogs, but every reference to the '60 I've found in print, pics or the web has it with the red glass and no overlays, just like the '59. There are some differences in the limbs (at least 2 variations) but they should be laid up the same.
I know the one '61 catalog I looked at listed it as 64". Should have bought the dang thing I guess, but I was focusing on the 50's.
