mouth piece question

2 George M Bundy Mouthpieces with his singiture and the number 3 on them but they look totaly different
one looks like a normal one, long skinny, with the 4 lines in 2 pairs on the bottom rim
the other is a little shorter and is as fat as a bass clarinet mouthpiece in the middle. in fact when i tryed it out I used a bassclarinet lig.

found both in the band closet, I belive the fat one is rubber
ill try for pic if needed

I just though the big one looked crazy wierd
