Length of SP15 Oscillator and steel rider

Hello everyone. I’d really appreciate it if someone could take the time to measure the length of an SP15 oscillator and the steel rider.
I appreciate your responses in advance.

Try posting on the Vanderblog at vandercookpress.info too

Or email/call NA Graphics and ask them if they have the diagram handy

Yeah, I posted it on the Vanderblog but no answer yet.
I’ll also email Fritz, thanks!
I just would like the measurement with a measure tape, nothing down to a thousandth of an inch.

The SP15 oscillator is 13 and 3 /16ths inches long and the ‘steel rider’ is 16 and 3/16ths inches long

Very kind of you, David!
That is quite helpful!

Did you want the overall length or the length of the face?

The tube’s length, Dan.
