Ford radio code please?

I bought an old Ford Transit van with a dead battery. On changing the battery I found the radio needed a code. Took the radio out and found it's from a different car (Fiesta 1.6 Si).
Radio model number is 2005, serial no M045751 (+Part No 94FP-18K876-EA). There's a hand-written label on the radio saying "V2371", but I'm loathe to try that and mess things up!
Thanks
