Pricing on 4 razors

Here is an add from someone selling 4 razors.

"the man who owned these items my family called grandpa fallici and he worked at the barber shop in new york city that was in the film dog day after noon w/al pachino, he worked as a barber there for a long time so you can imagine (with how old these items are) how many well known mobsters got a shave_and_a_haircut with them! :) most all the barber items have the boxes instructions and manuals receipts ect......I dont know how much there worth or how rare they are, ive only done a little research so make me an offer i cant refuse!!! / my camera sucks so if you need any more info i can take more pics of msg details. THANX! more pics upon request!

He doesn't know their worth and neither do I. I'm betting he thinks their worth more than they really are, does anyone have a ballpark figure on what I should offer him ? If I did this right, the pics should be attached.Attachment 113234 Attachment 113235 Attachment 113236 Attachment 113237 Attachment 113238 Attachment 113239 Attachment 113240
