Perf 14 x 14.75

4 post office sheets, each, single pane, 12 rows of 10.

After a brief appearance of the young farmers type B, the medium format reverted to type A for the remainder of the decimal period.

A most interesting feature of this layout is the Antarc 8d, which in appearance would seem to be yet-another layout. In fact, it is a mere (but cleverly done) type A printsheet with the central perforating pins removed to create such a large design.
