When this thread started I looked up the blue collar wage in 1975 and found it quoted as £48 or thereabouts on several sites. so taking todays average wage of £500 as the equivalent then a factor of 10 looks good – so a bare ML7 in 1975 at about £120 becomes £1200 – perhaps a bit low if these machines were still in production.
But there are two factors to consider – the cost of production which nowadays would involve CNC and less skilled and hence less well paid production workers and the easy availability then of quality castings and other materials. CNC machinery is a considerable expense to the manufacturer, but software and computer updates may give it a shorter useful life – compare this with the late John Stevenson who maintained that the machine that ground the beds of the latest Myford lathes was the same one that produced his 1947 model.
The second factor in looking at inflation is to consider what job role compares with what. A manual turner today would not be as common and may be seen a a more skilled technician and so not have the same status and pay as his previous counterpart ie he may be a specialist and paid as such.
In a different context, classic camera collecting, it seems to have become accepted that similar wage/price comparisons have no real meaning and I suspect that may be true with machine tools too.
