Just an interim update. And Thanks California for that thread - It is a good read and full of great info. I plan on running my new loader valve with PB to the 3pt. I have the Hoye power steering kit installed and when I went through that I found multiple places that can be used as a return to the tank on my tractor.
So, BLB is primarily in Italy, there are three distributors in the US- I called Beieler who is a BLB distributor and who I have worked with before and they told me that they dont even stock the parts so it all has to be ordered and then shipped overseas. I am more comfortable buying something that is off the shelf and more common. So I am not going with a BLB replacement. I did call VN tractors - twice - the parts guy was not available and the person taking messages struggled with taking my phone number down correctly. I doubt I will get a call back in any event.
So I puled the trigger on a Brand Joystick loader valve with regen, float and PB kit. I think it might be the same one Wooly purchased.
More details to follow.
