I have a  coax connector that I would like to identify. Se attached
picture.  

To the left is a female TNC for reference. The unknown male is  attached
to the cable. Unknown female to the upper left as part of a "T"  adapter.

It looks kind of a smaller version of TNC. It is slighly  larger than
SMA. Female diameter is 5/16", whereas TNC is 7/16" and SMA is  4/16" -
according to my simple measurement.

Anyone recognizing this  connector?

Hi Bjorn
 
Quick answer is no, but "miniature TNC" would seem to be a possible  
contender.
 
Unfortunately, although I've seen enough references to miniature TNCs to  
know they exist, I've not yet found a photo or drawing.
I'm pretty sure I have some equipment with them fitted but, if I have, it  
will be in storage so not something to be confirmed in a hurry.
 
What you've got, as you say, is certainly not SMB or SMC but is about the  
same size as SM.
And yes, that is SM and not SMA.
The SM connector, not very common but I've got some Greenpar SM  adapters, is 
similar to SMA, in terms of pin and dielectric arrangement, but  bigger, 
whilst what you have is a very close match to the TNC  configuration, but 
smaller.....
so, in size at least, they sort of meet in the middle:-)
 
A while ago I bought a Greenpar adapter kit that was a special  for the UK 
military and probably the biggest kit  Greenpar made.
Alongside most, if not all, the common connectors we're all used to was  
quite a range I'd never heard of before, including SM, HN, SC, Pattern 8,  Pattern 
12, etc etc.
They generally seem to be a "close but not quite" match to more common  
connectors but so far I've not seen any of them in commercial catalogues.
 
I suspect your connectors might be similarly unusual but still think Mini  
TNC is the most likely option..... although happy to accept that somebody will  
probably prove me wrong within a few minutse of this being posted:-)
