Fortysevenfan.....(top name.....my first ever job as a little apprentice on BR in 1980 was to work on 47 474.....12 heads and liners......25 years later and I still work with them, alas though poor ol' 47 474 has finally departed to the scrappy from Wigan
.....Sulzer 12LDA's Rock!).
Anyway....your dead right, give them some National Service, make the buggers appriciate what they have, and some respect for others and their property!.
Good on Ya!
Regards
