Default Broken Collins 51J-4 tuning slug question

Hello,
I just received a Collins 51J-4, ser# 7310. It survived a UPS journey
quite well. The only thing I have found physically is a broken tuning
slug core from L-114 inductor (which is a variable sliding powdered
iron core that is varied with the main tuning dial). The good part is
that both pieces are completely intact with no chips or chuncks
missing and the two pieces fit together perfectly with no gaps. The
break is less than a centimeter from the top where the tuning rack
"push-pull wire" enters. All other slugs look great. Can the two
pieces be carefully glued back together? If so with what type glue or
does it matter? It seems like it could be glued but if this is a
stupid idea, is there any hope of finding a replacement? Any help/info
greatly appreciated.
Thanks in advance, dave austerman, N5WNM, San Antonio, TX

Glue works fine. Use some of the water thin CyanoAcrylate
glue that you can get in the hobby store. You first fit the slug
together dry, and with it held together, add one drop of CA to
the crack line. The water thin glue will wick into the crack, and
the slug will be fixed.
