Bren Gun: Help Needed!

[Peter Laidler]

If you try to blue it it's an amateur job. If the professionals do it - it's a professional job! As I am not clairvoyant I cannot tell what process your local engineers use. It's your gun, do what you want. Your gun is an inert display piece. You don't need new wood. Just make good what you have without degrading the wood any further.
