After much cross checking between digits I have now settled on what I
believe the final measurements are and this is the result:

The left half will sit right on top of the right half so there is x & y
consistency between the two characters, the risk of the part fitting
Many thanks again,
@Christian - that is a sound plan, will do/
@Gregbert - noted though I never solder these things in, I make sockets for
them every time which makes insertion/removal and replacement relatively
easy. I purchase 40 way turned pin sockets and break the pin sockets out of
them
Make sure the holes for the display pins are larger than minimum; I made my
own footprint for the SP-151 and it was difficult to get the pins fully
aligned when trying to solder it in. Larger holes makes it much easier to
insert the display for soldering.
Also beware of the *glasshole*, as I
Can't help you with better drawings, but I can recommend 3D-printing a
small piece with the holes at the planned locations to verify the fit
before sending off the board for production. I've used this technique
myself a couple of times.

Have you asked Dieter if he has a better scan that he can share?

Thank you Benoit but I need actual data to make a footprint to use in PCB
design application.
I think I'm mostly there but was really seeking a better picture so I can
confirm the accuracy of the supplied numbers and to which pins they apply -
some of the ones buried in the centre of the
try to find 0.5 mm inner diameter pipe, 10cm long, fit all the pins, pour
some silicone, you should have a good representation of the socket... if
you didn't forgot to add some wax or similar to unmold the silicon.
the more parallel your pipes will be, the more accurate your print will be.

Oh, probably not since I misread SP-252 as SP-352. Apologies !!

Hello, there are indeed a few the line up - it's the ones that don't that
worry me the most!

Hello Richard,
have a look on the SP-351,

not the same number of digit, but some of the pins should be identical...
On my SP-356, there is 0 aligned pins on a diagonal way.
You could scan the bottom of one using a scanner and convert to inches/mm
using the DPI.
