Look at www.chicagopneumatic.com online catalog, pneumatic, drills & tappers, tappers, item 1241474 part 2F16-L-250, this is virtually the same but mine is a -300, ie 300 rpm
Look at member's shop 
baxter19730 for collets etc
Retailing on ebay and elsewhere without the quality Desoutter head for around £800 for a cheap & cheerful, to a reasonable quality unit at £1500+, this is a true bargain for a cost & quality conscious engineering company.
