A couple of C8A PERS-3 oddities

[cmperry4]

Just a couple of things noted during work in my HUP '45 "Staff Car"

1. The staff cars were equipped with the driveshaft drum brake, as with other CMPs, to quieten the driveline sound, according the Bart V's W&T article.
This superseded the cable operated rear drum brakes. What I found is the torque tube for the cable actuation still mounted to the cab frame, suggesting cab assemblies might have been well along the line before they made the switch to the driveline brake. Any opinions?

2. Both Rob Clarke and I have noted a hole cut in the floor for access to the upper transfer case bolts. His looks more neatly cut out than mine, which is a rather crudely peeled down opening (to be hidden under the lino flooring of the staff car). As the staff car transfer cases were mounted on rubber blocks (same type as forward engine mount), it would raise the bolt heads about and inch or so, so I'm wondering if this "access hole" was a crude, ad hoc "modification" made on the line, or something that would have happened in the field the first time the RCEMES had to drop the case and discovered the boltheads were darn-near inaccessible under the floorboard.
