9/32 drive T handle

[Tin Falcon]

I have what I believe to be a bit of a rare tool.
It is a small T handle with a sliding 8mm bar about 120 mm long it is marked H7M the square dive part measures 7.1 mm square by 8 mm long.
I googled 7 mm drive tools no info.
I purchased this thinking it was standard 1/4 .
So if someone wants it let me know.
Or if you are attending Cabin fever I can bring it there.
And I can do a picture if needed.
Just found a 150 mm or so extension and 4 sae sockets that fit this thing. IIRC they came from different places Marked Hins Dale on the extension.
OK found some more info. It appears to a be a partial 9/32 drive socket set.
Probably a Hins Dale 11M set
Looks similar to this

but no box. I will look for more sockets.
At this point make an offer if interested . These seem a bit collectible.But more to fill in missing pieces.

There is no case and only 5 sockets 1 T handle and 1 extension.
