Shooting and developing unknown black and white film??

[Tadhgo]

I just picked up a bulk film loader in a charity shop for €2. There is black and white film loaded in it but I have no idea what brand or iso speed it is. I've just loaded a film from it and want to try it out.
Just wondering if anyone has any idea how I should shoot it and develop it?

Maybe develop a short piece of it to see if there are any edge markings to identify the film?
