Re: Mismatched Endplates

I have an issue with the 'Indians were using the Italian tooling' argument. I think that over time they will have developed their own manufacturing processes that suited their needs.
This may have been the case when they were using up the stock of parts and moulds that they bought in the early days but we all know that the easiest way to tell an Indian casing is the five ribs on the flywheel side mount. This clearly says to me that they were not using the same mould to cast the MAIN engine casing (even though it still has Innocenti markings) so why would we we continue to maintain that they were following other original Inocennti manufacturing processes??
I'm not an engineer by any means but the 'perceived wisdom' is that the the Indians 'machined the endplate and the casing at the same time', but what does this actually mean? Does it mean that endplate is torqued and dowelled into the casing and then the hole centres in the endplate are machined through for the cluster and the layshaft or that the bearing faces are done first in the endplate and the gearbox assembled then machined the holes for the bolts and dowels?
Surely someone in the community must have a contact in SIL who could settle this debate once and for all on the Indian side, similarly there must be some record or contact who could describe the original Italian process??
