[Collins] Broken 51J-4 tuning slug question

[daveaust@pol.net]

Hello,
I received my first Collins rx today. It's a 51J-4, ser# 7310. I'm in
awe of its beauty(goofy, I know). It survived a UPS trip really well. I
am still in the inspection stage. The only thing I have found physically
is a broken tuning slug core from L-114 inductor. The good part is that
I both pieces 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 "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
