Recently bought off of Ebay.. It is an OEM master..
Although, I was told that it was good, it obviously isn't.. Upon mounting it and filling the reservoir, fluid pretty much immediately started leaking out of it and down the threads toward the break pedal ..

I went the easy way out and bought a $13.00 Chinese master.. No need for this stock worn out one..

For anyone willing to rebuild and revive it, I'll totally give it to you.. PayPal me five bucks towards the shipping..

My number is 909-206-7581
for shipping info..

Thanks
