strange dedicated lens hood

[Arnold Stark]

Today I was at a photo fair ("Fotoflohmarkt") here in Hamburg. I 
discovered a very starnge dedicated rectangular lens hood: The hood for 
the SMC Pentax 1:1.4 35mm lens!!!! So even if that lens was never sold, 
the hood was. The seller wanted 35 Euros which I considered to be way 
too much for an item that I well never be able to use, as I never can 
own that lens.. .However, I did buy a metal round hood for my 135/f2.5 
or 200/f4....
