When I recovered the sustaining pneumatic for my Simplex, it had a very
porous felt material over the top valve seat. It was too decayed to
reinstall so I left it off. Now I know why it was installed in the
frist place, every time the sustaining pneumatic operates you hear a
hiss. Can anyone tell me what would be a good replacement for this ?
Also I am looking for the Stars And Stripes Forever #45108 made by the
American company.

If anyone has one to sell please contact me at
