:: Hi,
::
:: Anyone know a mail order place where I can get those
:: screw-on job hanks that come on Quantum jobs? They are
:: white plastic bodies that screw through the luff tape
:: and then had brass pistons.
::
:: Of course, I could go over to Quantum's loft, but I'm
:: short on time this week.

:: Thanks,
