77H slide as a 6H back up slide

[gregwaits]

I was going through a lot of music gear when I came upon a Connquest slide section. The bell? I have idea where that ended up.

I play 6H, and have two very good horns….1852 and ‘56. Both slides are fine.

The 77H is also .500 bore. Aside from a brass crook I don’t see any difference.
Has anyone here used one on a 6H bell in a pinch? I’d considering selling this one (1965), since it is in pretty good shape. It moves smoothly despite visible plating loss on one stocking.
