Blessing B78 specs

[hyperbolica]

I've got a couple questions about Blessing B78, if any one is familiar with that model, especially compared to related conns.

Does the B78 have a slide tenon like the 88h or 78h? How about the slide width and the bell diameter? Any comparison between B78 and 79h would be welcome.

Thanks

Blessing's B7 is comparable to the Conn 78H. I believe the tenons are the same. The B78 is comparable to the Conn 79H.
