Need help T-5 experts!

Well, here is what I have and need some help to I.D. there is not a tag and I have searched the web for hours to find a Borg Warner 5 speed that looks like mine. I have no idea what it is out of I baught it at a swap meet. you will notice there is not a top plate inspection cover and no counter shaft bering on the front. It has a 10 spline input shaft and I belive 1st gear is 4.03

 

It is not a T-5. Might be a Tremec NV3550.

 

Looks like T50
