Earlier this year I struggled to figure out how to service my kitchen faucet. After removing it and replacing it (with a Dura-faucet) i had determined it is a Wellmade Faucet. Mine was
WMF EL-8201L-BN
I contacted the company with the issue I was having (Squeeky/hard to turn knobs) and they were of little help. So much happier with the new durafaucet.
Up until this point, i had not heard of this brand and wanted to share with the forum in case this might be the brand of yours. BTW, the branding/model number were on the bottom of the faucet (easy to remove though)
