If you take the fitting to a hydraulic shop they can easily ID it for you. I did have something to assist in working out what size and type of hydraulic fittings were used. I have never understood the BSP standards though.
Radiator, you can possibly get it re-cored at a radiator shop. Its worth at least getting them to have a look and quote you.
Bobcat mainly use JIC, others use ORFS, some use BSP, its really hard to say without seeing the fitting.
