This note came to Forkliftaction directly from Mike Lejeune, so I have added it here and we hope that it is helpful to this discussion......

Yard lift model 6024 is a Clark lift truck serial built also in Europe under license at Strasbourg plant and I suppose in Mülheim/Ruhr too.
6024 is engineering model name.
I can't remember this truck because in 1954 I ran with short.
I remember to have seen many 6024 record-cards from Strasbourg production at Mülheim factory.
Normally serial number of machine is engraved at right side of chassis at foot step vicinity. Apart from 6024 figure, you should find 6 to 8 digits corresponding to Clark's order number. These digits are needed for finding lift truck record-card so that adequate steering knuckle will be delivered.
Once complete serial number is found, please contact:
