Shaving brush help please

[PWA 1967]

Thought maybe i would start here if anyone can help me please.

The knot in one of my shaving brushes fell out this morning and not sure what to use to glue it back in.

Its more a sentimentle thing really as my dad bought it me years ago so i wont just throw it away and just needs glueing back in.

I have tried the internet as was going to phone the maker up to see what glue is probably best as the bristles were obviously put in some kind of resin.

Anyway they dont exist any longer so any help would be appreciated.

I dont want to put the wrong glue on and ruin it
