Hi, I am hoping someone can help me as I am stumped.
I have a very early Benjamin Franklin (c1935) that needs a silver solder repair. The repair is relatively simple - reattach the bolt unit to the barrel. However before I can do this the air outlet valve needs to be removed as heating will no doubt ruin it.
It looks like it need a very special tool.

Anyone any advice on how to do this?

Many thanks
