For the V-infinity supply, the part numbers are:
3-position shell with ramp: 09-50-3031
4-position shell with ramp: 09-50-3041
sockets: 08-50-0106
all can be bought from Mouser
How the part numbers for the Lambda supply were found:
1. The shell that was in the supply from a previous user had the following number on it: MXJ 5199
2. Google searches got hits on both MXJ and 5199. The google hits for the 5199 were for datasheets for compatible sockets on Molex's website. Oddly, the pins seem to also be compatible for the "SPOX" connector line which seems to have no resemblance to the header and socket type connector that I was trying to find information about. Handy link to the page that had the link to the 5199 sockets. The header shown looks just like the one on the supply: http://www.molex.com/datasheets/pdf/0010311038_PCB_HEADERS.pdf
3. There is a molex 5199 series document which seems to list specs for the pins: http://www.molex.com/pdm_docs/ps/PS-5199-001.pdf
4. Eventually I traced from the pins to the shell drawing pdf, which even showed the raised 5199 markings. This gave me the Molex part number which is 10-63-3044:

Note that the three part number is called an "EDP. NO." number while the 5199 is called an "ENG. NO.". The EDP number is the one that appears in distributors' lists.
5. Note that this connector is neat because pin 1 is offset from the others by a half a pitch of dead space in the shell.
6. There was confusion of the meaning of number of "circuits". It seems to mean the number of pins aside from pin 1?
7. The shell's EDP number was found at MOUSER but is not available.
8. The molex page for 5199 shows the sockets under "use with", options are 5225 and 5194. The links for these bump me to lists of series with 10-digit numbers with no dashes but which seem to be EDP numbers.
9. Plugging all the socket EDP numbers, with dashes put in at the 4-2-4 intervals similar to other MOLEX part numbers at MOUSER got hits for all, but only a few were in stock:
08-70-1031 is a part number for a bag of 5000
08-70-1030 is individual sockets of the same type
10. Note that the socket drawing from molex is at:
