Oneway chuck key.

Hi everyone, the arts centre at Milton Keynes (UK) inherited a nice Graduate lathe last year and with it a Oneway Stronghold chuck. Once I managed to get it wired in the lathe was a great addition to the turning workshop which is used for several classes each week plus the local turning group as well, until some kind but forgetful soul managed to loose, sweep up and throw away, drop into the bottom of their bottomless tool bag, borrow and then forget to bring back, any of the above or some other, the chuck key that came with it. So now we have a lovely chuck but nothing to work it with, would anyone have a spare Oneway chuck key that they would donate to the centre, we are a charity and don't have any spare funds for replacing lost or broken kit at present and all the students in my class would be very grateful as it would mean we could get on and do the real big turning that some of them are so looking forward to doing. Thanks in advance of any interest shown, Hotfoot
