It wouldn't surprise me to find out that the magnet was glued over the seam 
to strengthen the seam itself.  If you're going to be replacing the magnet, 
then maybe some tack welds along the seam before you replace the magnet 
would strengthen the housing.

Either way, I have to believe that the epoxies available today are 
significantly better than those available in the 70's through whenever 
Barrett Electric was rebuilding them.
