Yep that looks like it...That chassis runs the square head pin on the flap,and that piece on the front of the catcher for it to lock into is a giveaway.
Good score on the brochures...All my stuff only goes to 78.
So a model 29 it is...just seems funny they went out of sequence as model 29# id expect from the late 50,early 60s
Well deduced inspector Deejay:)
