Break Reservoir Window

[Rhandom]

The other day, I tried to white the cloudiness off of the reservoir of the front break, and it disintegrated. Any idea what the part number is to get a new one?
I've picked up a few 18mm ones from ebay/Amazon, and they are to big. the Original was press fit with a retaining clip.

Last few weeks with good weather, I'd like to get some riding in.

Thanks in advance for any suggestions.

Yea same crap happened to me too. I think these things are about ready to die nowadays.

Anyway there's a guy in VA - ebay newrivercycles - who makes and sells the little things - I may have met him a couple decades ago - and given him the idea - not sure, but get it from him and swap it in. LOL, and I lost the item I got from him and kluged up a remote reservoir on mine.
Cool.
