Help with a B & L lens

[inombrable]

Hi all,

A friend of mine asked me to help him value some photographic items he has, almost everything is cheap stuff but checking some of the pictures he sent me i saw a very rare B&L 75mm f/5.6 for argus C2 C3, he might want to sell it but the questions is HOW MUCH could this lens be worth?


here are two pictures (not very good ones) he sent me

Thanks in advance

Quite rare so there is no established price range. Its for Argus though so the collector expectations are for rather low prices.
I have seen a couple of these over the last 5 years or so go for $50-100, but since they are so scarce its not any sort of guide.
Put it up for auction and what he gets he gets.
