Foreign wood frame bellows camera

I am a retiree fromn EK after forty years but that was 22 years ago. Also my tenure was in the microfilm markets.
The camera that I have shown was acquired at a garage sale only yesterday, and was researched as much as possible on the internet. I was told by the seller that it was found in an old steamer trunk that was sent from Germany with miscelaneous items and was stored in an attic in Kalamazoo Michigan.
There were absolutely no identifying names or symbols, the only data was on the adjustment levers and etc. It looks well made and engineered, the bellows are perfect and it would take a 3 1/4 x 5 1/2 inch exposure.
