Lynx black cat 10.5 degree driver

[Huwey12]

I've dug out an old project from the shed. I can remember putting a graphalloy pro lite shaft into the Lynx black cat head but never butt trimmed to length
I thought I might complete the project started 7 years ago

The face is convex and the alignment mark is about a third towards the shaft, weird

Anyone ever seen or used this driver head so I know what to expect
