Well, the tubes themselves are here,
https://en.wikipedia.org/wiki/Tube_socket#Summary_of_base_detailsas for the sockets, you'd have to ask the manufacturer for a drawing. The pin tails could be kinked inside or outside, alternating or straight, whatever width...
Nice thing about pin-base tubes is, if you can't find a socket, you can always make your own with solder-in socket pins in a PCB. Not the best voltage rating, or least capacitance, but can be handy in a pinch, especially for oddballs like Nixies.
