I have used Cascophen Resorcinol (resorcinol formaldehyde)made by Humbrol to repair broken stocks for nearly thirty years now.
This stuff is amazing! (same as Aerodux 500)
I'm sure I bought the first lot in the US, when I lived there, so it must be available there.
Not cheap, but the best glue for wood I have ever come across.
Another advantage: it sets in a dark brown colour - just like a dark gun stock.
I have even used it on an old, VERY oil-soaked stock at the hand - although, for safety's sake, I also dowelled it.
Cascophene is used in yacht building and that s how I came across it.
They claim (and I have tried and proved it) that any two pieces of wood glued with it will break anywhere but not at the glue joint!
The important bit: it needs to dry for at least 24 hours (I do 48 hours) under pressure! (i.e clamped)
Make sure to use Cascophen (Resorcinol formaldehyde) and not the newer phenol or urea-formaldehyde glues (Cascamite for instance).
Just my two cents
