Charlies correct about the idlers there three types two wood and one cast, the four digit number is not a factory number but is valid... at least two, three and four figure numbers occur on some FTs in this position, I have no idea what for but the one at Bovi has 13.....
Cheers
Edit: Sorry I meant registration number here
