Hello David.
Thankyou for looking and it looks like you followed my footsteps through the mire.
Unfortunate that so much of nostalgia gets lost over time as most of it leaves the soul and substance lacking electronics of today on the garbage tip as it is not worth saving.
Managed to buy 2 x 'Crystal Sets or Metal Detectors' on Ebay and found when they arrived, that they were Eddystone 50/60 Mhz 5 Meter Band Transceivers.
Eddystone are well supported and found their source in their 1932 'Short Wave Manual'.
Was fitted out with a 30 and 33 but I was attracted to the beaut coils and geared dial etc.
Both had their Microphone transformers open circuit.
Just finished restoring a 1978 Yaesu FT-901D All Wave Transceiver and this was going to be used to drive a TMT (Tesla Magnifying Transformer).
This TMT is currently tuned passively and amplifying into my local AM Radio Station via Telluric means (through the ground) and not via the Hertzian means (through the air).
Always two means of gaining a result and in this case, one is free and the other you pay for so you know exactly which one we are using today.
Thanks again and hope someone else may see the Post and be able to assist.
All the best.

The only sketchy info I could find is on the Kelvin & Hughes Mk IIb 'Supersonic Flaw Detector'. This ancient instrument had not even been made by Kelvin & Hughes, but was built to their designs by some other company under a Ministry of Supply manufacturing contract.
http://www.ob-ultrasound.net/mk4.html
That info is from a website entitled ‘A short History of the development of Ultrasound in Obstetrics and Gynecology’.
http://www.ob-ultrasound.net/history1.html
It gives an interesting insight into the origins of ultrasound, dating back to the early 1800s through to the early 2000s. As early as 1826, Jean-Daniel Colladon, a Swiss physicist, had successfully used an underwater bell to determine the speed of sound in the waters of Lake Geneva.
None of which is at all helpful in answering your request for info on the KH MKV detector.
Kelvin Hughes as a company still very much exists, but seems not to produce diagnostic equipment – nowadays it involved in marine communications, radar, surveillance equipment for the military and so on.
Closer to home for you, 0n 26 June 2012, Kelvin Hughes appointed global defence prime contractor Austal to head-up its sales and service operations across Australia and New Zealand. KH says that the agreement will allow Kelvin Hughes to better meet the demands of its client portfolio across the region, which includes the Royal Australian Navy, the Royal New Zealand Navy and the Australian Customs and Border Protection Service.
It’s a long shot, but who knows – they may still have an archive of technical info so it could be worth contacting them:
http://www.kelvinhughes.com/
As to the Taylor 94B, all I could find was a picture of it on Radiomuseum.
One of the largest UK suppliers of technical info is Mauritron, from when you can download manuals. No luck there I’m afraid.
Sorry I can’t help, but at least you know someone tried.
Best of luck in your quest David.
As a footnote, I know what you mean about the 'stripdown value' of old equipment being more valuable than the sum of its parts. I have an old Marconi signal generator which would need major attention, but must have cost a King's ransom when new. Lot's of useful stuff in it - valves, valveholders, switches - even nuts and bolts, but also, much of it is specific to the instrument and no use to anyone. I always feel a bit guilty about pulling stuff to bits - almost an act of vandalism, but being pragmatic, it's sometimes either that, or just leave it to rot.
I've got an ECT machine that's nicely made but I'll probably end up chucking the innards away and saving the nice wooden cabinet, as people often did with crystal sets - arrrgh! However, there's no way that I or anyone else will ever use this machine for its intended purpose - for 'electro convulsive therapy' - a highly controversial technique which has its supporters and detractors. I'm too young to die, and too old for nasty shocks!
