Looking For DEC TTY Connectors

[O. Sharp]

Hey, all:

I'm looking for two pair of the sort-of-Molex-like connectors DEC used for 
connecting Teletypes to minis in the late '60s/early '70s. A DEC drawing 
designates them as "Mate-n-Lock" connectors, T04915; my web search for 
them turned up a lot of connectors, but not this type. Here's a photo of 
a set, if it helps:

Are these still manufactured? Does anyone have two sets in spares, or 
otherwise know where I can find a couple? 

Thanks in advance for any help!

              -O.-
