Info on a brand of clothing, DERBY, DETENTE

I've a sports coat length, lightweight jacket with 4 buttons & patch pockets that's made of mixed fabric. Outside the inner pocket it says, in capital letters, "DERBY," & under that it says, "DETENTE." The fabric label doesn't state where it's made.

Online, I've been unable to learn anything about this brand. Andy said the same & suggested I register & ask the participants.

So, does anyone have any information on this clothing line? Where were the clothes made?

Thanks, John
