the industrial RB211 is a very long way from one that flies.
i would suggest you get in touch with the RR learning centre in Derby, you should be able to find a contact on the website, if not let me know and i'll find you a contact.
The biggest problem you will have is that the metals are very valuable these days, so scrap value is high and they have a lot of precious metals hidden away for recovery, such as gold brazing etc so the melting pot is where most of them end up.
