Thanks for all the input.

I've also found in Hansard that the Minister of Supply was asked (August 1940) what grounds there were for taking control of EH Jones and what qualifications a Mr Farrell and Mr Muirsmith had for running the business. There is also a document about this, as part of the Defense Regulations 1939, at the National Archive but you have to visit Kew to see it and I'm too far away.

Taking all the comments into consideration it feels like the general view is that EH Jones (under government control) could have been marketing the machine as Sigma Jones during WWII, at the same time Elliot where marketing it as Excel and Ultra.

Hi,
I'm new to this forum, but hoping someone can help with regard to the history of the BCA jig borer. I'm current restoring one of the Sigma Jones variants and after reading the information on the lathes.co.uk site my initial understanding was that the machines were first made in the UK as Ultra & Excel sometime around the beginning of WWII, then as Sigma Jones from 1947 and finally becoming BCA in the mid/late 50's. However, I've recently seen a Sigma Jones for sales with a stated date of manufacture of 1939. Re-reading the data I can find on-line I'm now confused. Tony describes the 'early' machines as Ultra/Excel, but uses 'also' in reference to the Sigma Jones, implying they were contemporary. But then going on to link them with the Herbert acquiring Sigma Instruments in 1947. Can anyone please clarify the periods when machine was marketed under the various designations?
