Unfortunately, 15495 doesn't tell me any more than it told you... ;)

I would recommend that you take the handle over to a local plumbing supply wholesaler and see if they can help you. If they are unable to identify it then they may be able to recommend a suitable universal fit set of handles that will do a good job in replacing all the handles.

Good luck!

In addition to Mark's advice: If you snap a photo of your faucet trim, and another one of the handle itself, and post it here - one of our Experts may ID it. Back to you. Milo
