Boley & Leinen lathe from 1943 

this Leinen 130 mm x 500 mm LZ43 is shown as manufactured in 1943
From it's introduction the L4 was continuously developed and improved with several changes to the drive system and stand was well. Although the apron and screwcutting gearbox were different, the headstock, bed and compound slide rest of early versions were remarkably similar to those used on the lathes made during the 1950s and 1960s. The first stands, in heavy cast-iron, were well appointed, having both a full-length wooden tool tray and storage for collets and changewheels beneath.
