Need Seroco lens & viewfinder

I just picked up a Seroco 4x5 that is in nice shape. It is missing the
viewfinder and the lens had been replaced.

Any idea where I can look/post to try to find vintage camera parts?

Thanks gang!

In a word: Ebay!

I found the triple convertible that goes in my c.1910 Conley (Seroco) on ebay, and then I found a twin of the camera to replace the one broken strut mine has. Just be patient, and you'll probably find a parts donor for your camera. Good luck.
