[Amps] Tube Physical Sizes

[Mike Selfridge]

A friend asked me if there was a place on the web that had tube 
dimensions.  Electrical characteristics are relatively easy to find, but 
not physical sizes.  I thought I'd help him out, and ask the question 
here.  He was specifically interested in the following tubes:

3-1000Z
3CX1200A
3CX1500

Does anyone have one of these they could measure, if not a web address for 
this information?

Thanks.
