ID Frame Fittings

I am building a frame from some rather old stuff. Not for anyone specific but it's time to use some of my stash. I have the imaged lugs, shell and crown but can't remember (or never knew) the brands or model names of them. Here's a shot before cleaning up and the small contour work i have done to them. If anyone knows their origins I would be grateful to learn them. The lugs are presses and welded, the shell is Eng thread and also pressed and welded. The crown is cast and fits the older Reynolds blade shape. (And the tube set is Vitus 172/171). Andy

Those are Prugnat lugs and a Haden shell.

Thanks, I'll post a finished bike when it's done. Andy
