Mike Borrow and Mike Humphrey can be seen in image 1 with, what appears to be, Joseph Salim Peress during tank trials at the Admiralty Experimental Works (Haslar) circa 1974. Others in the image are very likely to be David Denison and David Hibbert from DHBC Ltd.

Mike Webb’s first job after joining UMEL was to make Mike Humphrey’s designs a reality, which involved producing limbs for his personal fibreglass bodied SAM, shown in image 12. Andy observes that this clearly demonstrates the early signs of Mike Humphrey’s vision of a more anthropomorphic ADS. Mike (Webb) appears in image 3, busily machining the outside spherical surface of an elbow enclosure using a radius turning attachment on a centre lathe.

In image 4 Alan Ette (Universal Miller) and a colleague are seen carrying out a trial assembly of arm ring adaptors on an early magnesium alloy JIM torso at UMEL, Farnborough in the early 1970s.

Among JIM’s many original features were the oil drain holes which are clearly visible in image 8 and the (not too successful) finger manipulators in image 6.

But, before looking too closely at the images, it might be an idea to check out these hotspots first as they could help you detect other differences between the early JIMs and later adaptations.

Last but not least, the above video provides a compelling comparison between the ADS and the diver as they each try to make progress against an 0.8 knot current. Notice the amount of effort the diver is having to make, as indicated by the bubbles he is producing, compared to the ease with which JIM manages the task. Could this be why the diver, seen in image 2, appears to be looking a bit glum?
