Wartime, home made silencer

[Flying10uk]

I remember that when the chap was showing me his homemade silencer/suppressor he explained to me that it worked in the same way as a silencer on a car exhaust. I don't know how correct he was with this statement but that is what he said to me.

I suspect that when he needed to make the suppressor during WW2, that he only had a very basic idea of the general layout of the suppressor and much of the details he worked out for himself. I remember that the item appeared to have been very neatly made and that he had had it blued. The alignment rod was probably his own idea but I do remember him explaining to me that it centred on the bore and then the baffles were centred off the rod.
