New poster here..Pic of Key for Lab Volt 187 Variac Classroom Autotransformer?

[itsme_Bernie]

Hello All About Circuit Folks
If I am asking a question answered before, I apologize, and I would appreciate the name of the thread or link so you don't have to go through explaining again.
I am sure I could "hack" it, but I have a small machine shop and can fabricate a key if it is simple enough, which I suspect.  If I can leave it original I can keep to hacking my other belongings ha hah.
I cannot find a pic of the key anywhere. Do any of you happen to have a key like it, and possibly post a pic? Do you know how thick it is?  Other dimensions? 
Or do you happen to have a pic or know where I could find a pic?

Thank you so much for your help

Bernard

That might not be a key but a switch with a missing toggle bit.

I found an old pdf with a picture of a similar LabVolt 187 AP supply that might help.

Good idea, but it appears to be a key.  Here's a picture of a newer model with the same keyed switch.

A little searching showed nothing LabVolt specific, but that "keyed" switch is not like a real keyed switch with a coded key, but more like the safety keyed switch used by Craftsman and Jet  (and others) for their saws.  They are generic keys with no code, except when removed, the switch is locked off.  Here's a picture of the Jet version.  Craftsman's is similar.
