In the early 1960s a different Dial Type, the ELR, was introduced alongside the established models. Available as the  207-12 and 307-12 these had, as standard,  controls at the front only (rear controls were extra) and reverted to simple lever instead of push-button operation. Available in the usual horizontal, universal and vertical types, the model can be instantly recognised if fitted with rear feeds - the sockets for the two detachable crank-handle being reversed in comparison with the older machines such that the one nearer the front was set higher than the other.
All versions had a table 59.25" x 12.25" with 28 inches of longitudinal travel on the type 207 and 34 inches on the 307. Cross travel on the horizontal and universal types was 10 inches, but 12 inches on the vertical. Vertical feeds varied: 19 inches for the 207 and 307 in horizontal form reducing to 18 inches if a universal. The vertical had 13 inches as both a 207 and 307. All versions had a 7.5 h.p. motor driving 22 spindle speeds through a range of 21 to 1485 r.p.m. The table, as on other Dial Types, had an independent 3 h.p. motor to give 16 rates of table feed from 1/2" to 60" per minute as standard or, optionally, 1/4 to 30 inches - the speed applying to both longitudinal and cross travel with the knee set to move half as fast. Rapids were standard with a rate of 150 inches per minute horizontally and 75 inches vertically..



207-12 and 307-12 Horizontal Dial Type of the 1960s. This version is fitted with the optional rear controls, but with the crank-handle sockets a mirror image of those of the other Dial Types

Type ELR vertical without rear controls
