Hardy Fly reel Spool ?

Any Hardy users able to give me some help identifying a spool, please? Picked one up in like new condition somewhere, sometime back and I do not know what model it was made for.

It has the smaller shaft of the newer reels and fits exactly on a GLH Ultralight 8/9 reel, but is too thin for that model. It also is almost the right size for a Marquis Disc 8, but the disc system stops the spool from going all the way on... and the rim would not fit over the frame if it did close together.

The rim is exposed which eliminates a bunch of models, also. Some other reels close that I tried were St Aidan, standard Marquis in 8 and several others...

The face is ventilated, but the back of the spool is solid. The rim is polished and the recessed face is almost black with the usual Hardy latch system.

Anyone have any thoughts about what it is? Thanks for thinking!
