RB 1029, test 50921, of January, 1955 - New Zealand.
Next I'd like to itemise features of the known machines within each batch. For example, three machines in the final batch (A 2776) have RD/RM type fences, complete with handwheels for adjustment. RB 921 in the previous batch (A2684) has the RD/RM fence, but without the handwheel. So it appears that only the final 48 machines - and presumably the five "stragglers" - a total of 53 machines, came with the handwheel feature.
Cheers, Vann.
