Pre-unit A Group. The long stroke A7 had 2 separate rocker boxes with circular inspection caps that unscrewed. All the later models used a large 1-piece rocker box with 2 large inspection covers. Although there are 7 different rocker boxes listed in the parts books, after inspecting our large collection of used ones, no differences could be found. Initially no rocker oil feed was fitted and the first supply was to the exhaust only, from engine number XA7 450. In late 1948, from engine number YA7 3402, a new pipe was used that supplied the inlet as well as the exhaust. This pipe was used on all plunger and rigid models. The 1954-59 swinging arm oil pipe is similar to the plunger version but in 1960 it was split into 2 parts connected by a short length of rubber pipe.
