Checked with Neumann: No K49fet, but maybe the poster mixed it up with this one:

Part # 514753 K47 FET  (TLM49) 
v.s.
Part # 053223 K47 FET (U47 FET)

According to Neumann, they both seem to be identical, though the latter is about $20 more expensive.
(Who was it who made fun of Neumann's capsule pricing on this fine forum before?)

Thanks a lot for this ! I actually called Sennheiser USA and emailed Neumann, and no one got in touch with me... I'm glad you are here. So this could be it, this "K49FET'", could be a "K47FET" with the backplate wired, as the TLM49 is leaning towards hypercardioid, when the U47FET is not. Could that be the explanation ?

They were both explained to me as being identical in function and design.
So your assumption is either based on your superior fact finding abilities, compared to what I could accomplish, or is erroneous.

In fact the Neumann published polar diagrams of the U47fet  show a hypercardioid,  the U87 and others a cardiod pattern.

Well I'm just trying to guess why they have two identical parts with different number. But as much as I wish I had those abilities, even more I rely on your expertise. I guess I will buy it, and I could post pictures on this thread, if anyone is interested.

This discussion focuses not on Braunmühl-Weber double backplate capsules, as used in U87, but on single-backplate, K47-types.
Both types are incompatible in their polar and frequency responses.

So I went to Sennheiser Canada today, and guess what was in stock ? A K47fet ! Now I "just have" to install a wire on the rear side. Let us stay calm...
