Tachometer for my VW Bus

Here's my Tachometer for my 1977 VW Bus.
I got it at the dump in North Carolina.
Evidently you can drop your old boat or just about anything.
Eventually it gets smashed up and disposed of.
When me and my Dad were at the dump, we decided to
take the entire gauge cluster. I figure the boat was from the late seventies.
The tachometer had a look that will hopefully blend into the bus.
Free, is a good price for the Tachometer, if it works.....
