Where were the Clayton Type 1s actually built?

[Western Sunset]

Now I have both the two main books about these locos, but I've never been able to fully grasp one point. Where were the locos actually built?

Was it at Clayton's works in Hatton, or at the International Combustion workshops in Derby? Or was it a mix of both? Were components made at Hatton and the final loco assembly was at IC in Derby?

Any ideas, please?

if you believe wonkypedia : production of locomotives D8500–D8587 was performed in-house by Clayton, with subcontractor Beyer, Peacock and Company of Manchester delivering D8588–D8616 between March 1964 and April 1965

Thanks. Though by the time of construction of the Type 1s, Clayton were part of the same group as International Combustion. The Clayton Cuban "Brush 4s" were assembled at the IC works in Derby and photos show some Clayton Type 1s there too. Hence my question.

According to the DTG website (owners of the preserved Clayton) they seem to have been built twice-firstly at Tutbury then broken down and transferred to Derby for final reassembly

Many thanks Grumpy; very interesting. Though from the DTG blurb, I wouldn't have said that the IC works were "near Derby station".

Were Class 15 locos D8210 to 8243 not also built by Clayton, fitted likewise with Paxman diesels? It was normal for orders to be placed with the mechanical parts builder, who would bring in the diesel engine and electrical gear manufacturers as subcontractors, but with these locos for some reason it was done the other way round, the order was placed with BTH, the electrical gear suppliers, and they subcontracted the loco builders. The first 10 had been built separately, by Yorkshire Engine in Sheffield. This article says the remainder were built at Hatton, and one would think a facility that could do that would handle a follow-on order for similar size locos with some common parts the next year :

This design was another of the ‘Pilot Scheme’ diesels that was not so much a failure in design, but a product of the lack of clear definition of requirements, and the reliance on the electrical ind…
