This cabinet was one of Clarks display cabinets !! The last drawer would have had ONT on the front !! That was a Clarks brand called “Our New Thread” or just ONT !!
The best of these depending on size can bring $500. and above in mint condition !! I would expect yours to bring about $150. in its current condition !!

I believe this one is quite similar to yours !! The condition of yours is pretty rough and will affect the value !!
