Looks like a Bull Dog 4x5 from England, I believe. It is a DIY kit made from brass and MDX board. They also make an 8x10 version. www.bulldogcameras.com
I'm struggling to see any similarity with the Bulldog whatsoever. Can you explain what you're seeing that is similar? This appears to be a metal camera (sans the handles), whereas the Bulldog is mainly timber.
