It's a very nice piece, came with an aluminum washer. Seems to have sealed well, no signs of leakage yet at least....
No groove to put reflector in, but oil level is very clear to read without it. I'm happy with it, just wish the dollar was a bit stronger compared to the pound... the exchange rate made it quite expensive.
