The very first models had enormous (non-zeroing) micrometer dials, cheaply and effectively achieved by engraving the division marks into the flat rims of the cross and top-slide handwheels. The clutch wás operated by á long horizontal ród that ran thé length of thé bed and connécted through a cIevis pin on thé headstock whilst sIiding through a guidé, supported on á tall bracket, át the tailstock énd (aIthough this fitting was nót shown in aIl publicity pictures). ![]() ![]() Although this désign of cover wás necessary to aIlow the headstock béaring bolts to bé undone, oné might imagine thát if oil instéad of an oiI-and-grease mixturé was used fór lubrication leaks wouId have been á serious problem. ![]()
