Thanks Tony. Yes, the data plate looks original but, I meant that it could have been from another engine. Although engines were rebuilt and parts could have been exchanged, the basic ID of an engine is the crankcase, the largest single component. I suspect that it is impossible for me to be certain without a partial examination of the engines, and that is not going to happen (I saw them there as a visitor about 9 years ago). I do think that it is possible that damaged/used/overhauled or, on-production bombing damaged/reclaimed or, post-war assembled from several engines are possibilities. I do not aim to cast doubts here, these are just observations. Cheers
