I too, remember the London Science Museum from many visits in the 60's / early 70's, and share Robin's and David's views on the matter.

I once spent half a day in a magnificent industrial museum in a former dockside warehouse in Bristol. The technology was exhibited so it could be studied at close range, if one wished. I particularly recall aero engines mounted openly on plinths so you could look at the construction in great detail. I don't think it's there any more, at least in that form.
