The 50mm f/1.5 Nikkor will use all the 40.5mm accessories of the 50mm f/2 Nikkor.
I've never seen a Nikon hood marked 50mm f/1.5 however, not even in the books by Robert Rotoloni. Indeed, it was only made for one year.
Maybe the prewar Zeiss lens hood for the 50mm f/1.5 Sonnar will fit. I have that shade and that lens, but unfortunately not the 50mm f/1.5 Nikkor!

Many thanks Erik,for that information.
I do have a very nice post-war German black Voigtlander screw fit 40.5mm f=50mm standard hood (310/41) and it seems fit.
