I actually have an OE set of paper instructions that are on the shelf next to where the hubs were. Probably put them there after I installed a previous set…in the last century.😛
Wow! That is WAY obscure. I wonder what the engagement mechanism is like, if it’s anything like the thumb screw ones?
Do you have Fairey hubs in your collection Drake?
The print looks totally legible to me. If you pull the lever arm out, spin it 180 and lay it back down, it won’t say lock any more.
Edit: perhaps you were only looking for the brand. That has been covered.
