INS-1 Neon Dot Tube Lead Spacing?

[The Doktor]

I'm hoping somebody here can help me. I am designing a circuit board for my own Nixie tube clock using the Russian IN-12 nixies with four INS-1 tubes as Colons. And ESP-32 to sync to NTP. I need to know the lead diameter and Lead spacing so I can put an appropriate footprint on the board for each tube. I purchased 100 of these tubes a while back very cheaply, and would just measure them, but they have currently Gone Missing.

 If any of you can supply this information it would be very helpful, as those Footprints are all I need to finish making the board. yes, I have tried to Google this information, with no luck. I can find the tube length and diameter, as well as the current and operating voltage, but no specifications on the leads.

Thanks

I'm measuring a thickness of 0.4mm and a spacing of 4.8mm
