Mugen ported cylinder ?

[JohnBeton]

Hello Guys,

Does any one know if mugen used to do portwork on stock cylinders ?
Today I was searching trough my parts and noticed an engraving on one of my spare cylinders, i never noticed it before.
I bought it in a partslot years ago and never noticed it had an engraving. When I took a close look, i saw it was the mugen logo :eek:

I attached some pictures of the cylinder, i will try to make pictures of the inside.
