Hello, I'm writing you from Montevideo, Uruguay. We have recently dismantled an entire SCADA system with PDP's, rm03, etc. I have some spare parts for the rm03 (heads) and i was wondering if you or anyone you knew would like them. I have a lot that are used and six new, in the box and sealed. I also have an aligning disk. Sebastian Boccardi Autotrol Uruguaya S.A. Montevideo, Uruguay
