Sorry unable to help you out, but I also like the early photos.
I have done a few digi to retro myself and they come out OK, but I realise you are after the real old stuff. Got to love those 'Flapper Girls'
I have added a couple of scans I have done, one in the 'Sexy Monochrome of the Hour' thread and another in the 'Fake Retro pics'. Both found in the Misc Fun threads. I just put on them Digi2Retro. Good luck with your hunt.
