I'm looking for Ronthor drawer guides

A quick learner says:
Searching for drawer guides for the top of a bar cabinet chest. The front of the guide has patent 2857233 and the back has RONTHOR N.Y.C.. I have had the bar for 47+ years and there are no identifying labels or numbers on the cabinet. It is solid wood. The runners are on the bottom of the counter top, also solid wood. 1 in across, the lip width is 1/4 in. None of the guides at Lowes will work because they are too tight.

Hello!

Based on the design of your guide, I recommend the 32-031 but you'll have to compare our dimensions to an undamaged version to confirm this matches up to your old hardware.

I don't have an undamaged one, just the bottom part I sent photo of. What is your return policy if they don't work?
