A friend got this new/old valve and is not sure what it might have been used for. He wants to know so he can possibly sell it and market it to the right airplane. I said, hey, maybe somebody on VAF will know what it is or want to buy it for their project. Its a nice valve with smooth action. He thought the ports were 3/8".

Looks like you can buy a very similar one from skycraft - note the price.
Never heard of the "bolkow" aircraft - looks like they had three models according to wiki...
