I acquired MY Rocksport Buggery Box in 2017 as part of Bob Thrun's collection.
The Rocksport Buggery Box is 155 mm. tall, 49 mm. wide, and 30 mm. thick, and weighs 314 g.
The fixed plate is made from 5.5 mm. aluminum alloy, and the swinging side plate from 2mm. Unlike most bobbins, the swinging side plate on the Buggery Box pivots from the upper bollard bolt. An arcuate notch clears a shoulder in the lower bollard bolt. The lower ends of the swinging side plate is bent to converge at the attachment point, which is a 15.2 mm. hole in the swinging plate and a 16.0 mm hole in the fixed plate.
The bollards are turned bronze. They are bolted to the fixed plate with 5/16" (~8 mm.) bolts. Two small (~3 mm.) hex cap screws passing though the fixed plate keep the bollards from turning.the top bollard has a flat-bottom V-groove. This bollard has a major diameter of 37.9 mm and a minor diameter of 25.7 mm. The groove is 12.1 mm. wide at the outer diameter and 4.9 mm. at the flat. The lower bollard has a U-shaped groove. It has a major diameter of 37.9 mm and a minor diameter of 25.3 mm.
The bolt heads have "HS," "NS," and "R" in raised letters.
The Buggery Box is fairly crude. I don't know when Bob got it, but I assume it was on his 1976 trip to the U. K.
Unlike most bobbins, the swinging plate on the Buggery Box pivots from the top bollard bolt. Also, the seat attachment points are holes with no quick-attach feature. Either of these "features" makes the Buggery Box less suited for common rebelay maneuvers, since the box must be removed from the harness to open it to remove or install the main rope.
