The machine Serial Number on US-manufactured examples is stamped into front of the knee casting--not the head (the head numbers are a completely separate series and have nothing to do with machine numbers).
On machines made in the UK by Adcock & Shipley the number should be on a plate inside the column door - the last 4 digits being the date of manufacture.
To find the Serial Number  on US machines, wind the table inwards as far as possible; the sliding guards should then have moved sufficiently to expose the stampings. The numbers below apply to the Series 1 models - the special and modified machines (such as Synchro-Trace Duplicators), used a different sequence (and some of these may have been converted back into ordinary types)..
