What does the internals of a BECO 1011 butt set look like?

[RotoTech99]

Dear Forum:

Does anyone have pictures of the internals of a Beco 1011 rubber butt

test set, please?

I'm in the process of getting one, and I'd like to know what they look like internally.

If a Forum member has one of these, can you send pics of the internals, please?

Thank you,
