I rebuilt an older version of that lathe, one before Houdaille bought them. Overall, not as good as a SB heavy ten. Has some good points, can replace drive belts without disassembling the headstock, variable speed, ball bearing spindle. Carriage design poorer, does not use tapered gibs, oiling points very poor, had to replace a number of parts and bearings because of this. Feed clutch sensitive to wear, there is no adjustment. Gear box mounting cannot accommodate bed and saddle wear.
History has it that when Houdaille added Logan to its mix, Logan was not treated well and wound up being closed down mid 1980's(?).
In Logan's favor is that Logan is still in business as Logan Actuator and can supply repair parts.
The one I rebuilt I finally sold for $1650, that was after redoing everything including regrinding the bed. $800 to $1000 would be reasonable.
