[Laser] Looking for Dumont 6911 Photomultiplier info

[Kerry Banke]

I recently picked up an RCA 7102 and a Dumont 6911 PMT which both have S-1 type responses. I found the specs and base diagram for the 7102 but so far not for the 6911.  Does anyone have info on the 6911?  I'm also looking for a 14 pin socket fo that PMT. I hope to try  both  of these for our NLOS  communications experiments in the 910-940 nm range. There are probably newer/better PMTs out there for this purpose but  so far haven't seen any on the surplus market.
  Thanks - Kerry N6IZW -
