It appeared that during factory collimation the thread had been mashed and without a collar to stabilise the tube collimation was unreliable. Not consistent with what appears to be, good quality fabrication, otherwise. Richard Taylor was receptive to the feedback, however.
You raise a good point, there have been quality issues with the polar scopes on the AT.
