Refixing meter glass.
I've got a 1940s-era milliammeter made by General Electric - the glass has come detached from the bakelite casing.
In the past I would have reattached it using "Durofix" but my remaining tube of this has gone hard in the decade and a half since I bought it, and Durofix doesn't appear to still be available (banned because of its high aromatic-solvent content?).
What to use ?? - I'm reluctant to use modern superglue as I fear it may set too 'hard' and increase the risk of the 70-odd-year-old piece of glass cracking.
