Cool !
I've had that same timing light for decades, dirt-simple and reliable as an anvil.
I still have and use my old Chrome Craftman bought when I was still high school age.
I think many still use them as well.
I must be a nut but as places closed down I grabbed stuff up.
Have a head light adjusting system from an old full service gas station.
It sticks on to the bulbs and has bubble levels .used it 2 or 3 times only.
And two static tire balancers I used to use it a good bit. But now just now and then.
