Hey blumby, thanks for that,what one would you suggest is the more disirable to do up? I have already stripped the model 5 series 1 and have started blasting bits and cleaning up, I bought one of those on bench sand blasting cabinets, and am running Garnet through it and seems to be bringing things up real well. and yeah the spare engine number is 94828 so I asume it be a series 2 Rotomo so 56-57
