@jeallen01
Thanks for your response, but yes, that much I know.
I was hoping someone might know who the manufacturer was?
It is very robust and the design is similar to the Jaeger but the moving arm appears different.
EDIT
@RustySpoons
Thanks too for your response.
Is that a confident suggestion or a vague guess? It does have a Jaeger type appearance. How would I tell the difference between 99G and 128G?
EDIT2
I've looked up some photos and it does indeed look like a
Jaeger Supermount 128G . Can anyone please confirm that?
