Yes, I think it might just be neo-Jenson based on the few letters in your links.
Strangely enough, I had come across Derringer but discarded it because of the curved arms, legs, bowls, etc.
Now, if I could only get a sample of the few letters I need of neo-Jenson, I could redraw them properly and get this out of the back of my mind.
Thanks for pointing me in the (hopefully) right direction.
