Help identifying what camera this might be?

I was given this 5x7 camera a long time ago and it's been sitting on my shelf just gathering dust. I have decided to dig it out and see if I can't find the parts to complete it -- it needs a lens and shutter and a back, but otherwise it looks to be functional. The bellows appear to be light tight and it's a really pretty thing, prettier once I refinish the box.

Problem is I know nothing about the big stuff -- 4x5 is as large as I go -- so I have no idea what make or model this is, and Google image search doesn't help at all. There are no markings at all on the camera itself, no serial, no maker's marks, nothing that I can see without disassembling it.

Maybe someone here can help me figure out what it is?

Looks a lot like a Seneca #9 with a replacement bellows? http://piercevaubel.com/cam/catalogs/1906senecalp317.htm page 10.
Another contender is the National Washington http://piercevaubel.com/cam/catalogs/1907nationallp297.htm page 16.
Check the turn of the century catalogs http://piercevaubel.com/cam/catalogs.htm for other possibilities.

Thanks. Those both look exactly like this. Kinda makes me wonder whether the National and the Seneca were made by the same manufacturer and sold under the different names, like those Cosina 35mm products that were sold as Cosina and Konica and whatever else they sold them as.

That catalogs site could get addicting. Must.close.the.tab.now...

(edited to add: Yes I finally read the tiiiiiiny little print at the top of the page on the National cameras -- National sold rebranded Seneca cameras, so yes, they are the same camera. I still can't tell whether mine's a Seneca or a National one, but it's the same thing.)
