Hello Richard, have a look on the SP-351, https://www.tube-tester.com/sites/nixie/data/datasheets/SP-351_SP-352-drawing-01.jpg [image: SP-351_SP-352-drawing-01.jpg] 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. only in horizontal.
