2FT 8.5" Gauge Loco Works Photo - Kent Cement Railway

I thought I would post this original works photo here which I acquired last year and I think it is quite rare. Its kept inside a book and nobody sees it and is a beautiful sepia photo and the clarity is stunning.
It is of a Locomotive built for the Bevan's Cement Works at Northfleet Kent in 1902, what's interesting to me is that this loco is mentioned in 'Cement Railways of Kent' as having been built by Hudswell Clarke as 631 of 1902 as Chapman and Furneaux were in difficulty, but what can be discerned from the works plate which is very clear is that it was built by Chapman and Furneaux 'successors' to Black Hawthorn and Co.
Does anybody know more on the history of the Loco builders? I should mention that other locos built to the same design were Meteor, Aerolite [ Black hawthorn], Satellite [ Chapman & Furneaux ], Rocket,Comet [ Hawthorn Leslie] all for Bevan's, then some were transferred to Alkerden Clay pits Swanscombe and Hawthorn Leslie building another 'Rocket' to the same design.

 

According the the "Black, Hawthorn & Co." Works list published by the Industrial Locomotive Society, PLANET (which was CF 1215 of 1902 and their last locomotive) was built by Hudswell, Clarke & Co Ltd, of Leeds (as HC 631 of 1902), as their Chapman & Furneaux had run down their works at Gateshead to point where they were nolonger capable of building locomotives. As it was built by Hudswell, Clarke for Chapman & Furneaux, I assume that they had their plates fitted to the locomotive, before it was sent to Associated Portland Cement Manufactures Ltd, Bevan's Cement Works, Northfleet, Kent. No need to tell the customer that someone else built it, they might decide to order spares from Hudswell, Clarke!
However by November 1902 Chapman & Furneaux had sold their goodwill, drawings and patterns to R. & W. Harthorn Leslie & Co Ltd, of Newcastle.

For these interested PLANET was scrapped c1943.
