Would this stamp on bravo prop indicate it is lab finished Thanks

It has been worked by DAH, which is (was?) a respected propeller shop.

Many years ago I had several props labbed there. John Janaky used to work at Mercury Racing was quite the character and knew what he was doing. Later his son Jeff took over the business and a while back they sold out to a guy in the Fox Chain O Lakes area. I have never tried the "new" DAH

Thanks Markus
