Great stuff in this thread Bruce, including your supersizing your order of the double deluxe transmission.

I would never have thought to take a Wilesco current production whistle and make a shutoff valve with it.  Nice.

I guess the one you used was similar to: https://www.ebay.com/i/333800981356

Thanks Scott.
I had a baggie with several old stock (Metal) whistles, the one thing that seems difficult to find is a Wilesco throttle valve that actually has a parallel or positive on /off location, Wilesco tends to not care where the handles ends up for open/close....
mine was more like this one ...
