Hi Bob,
    I don't remember an add-on locking mechanism, but seems like the locking 
pots had a shaft bushing that extended further than normal, was slotted, had 
a tapered OD and a tapered nut that screwed down on it, thus squeezing the 
bushing down onto the shaft & locking it.
    Hope that's clearer than mud.  Was there an add-on?
    (p.s. got one of those TR-4's going)
