Isn't this the buffered expansion cable?

So, I just picked up an MISE from Bartlett Labs (cause I really liked
the M3SE I had) and decided to revive one of my TRS-80 MOdel I's.
In my box of "stuff" I found an interesting ribbon cable the function
of which I don't know. It is a 40 pin to 50 pin ribbon cable with a
black box connecting them that is labeled TANDY. I know of nothing
the Tandy made that used a 50 pin connector other than a hard disk.
Could that be what this is for? Anybody ever seen one? I no longer
have any Tandy External HD's but then, with things like MISE and FreHD
why would one still want one other than for nostalgia.

Although I never had one, I beleive Tandy made an adapter that plugged
into the Model 1 expansion bus (40 pin) and gave you a (cut down?)
Model 3 expansion bus (50 pin). As you suggest it was commonly used
to connect Model 3 hard disks to the Model 1, but I think it worked with
some other devices too.
