1950's sealed source info please!

To whom it may concern,

Our (erstwhile waste) broker says he may have found a home for a 
no-longer-used sealed source.  It's a Cs-137 source in a Kellogg Kel-Ray 
CB-122 radiography head, the serial number (either of the source or the 
radiography head) being L-0884.  We've got lots of license letters, but 
apparently no manufacturer's literature from 1958 (or before?).  He needs to 
know how the source capsule is sealed - whether it's brazed or welded, or 
whatever.

My deep gratitude to whoever provides the answer!
