Default Need help indentifying sleeve

I got this in a lot of Go parts but it is not a Go. I am not sure on the bore size but it is bigger than common long stroke motors.
Pay no attention to the rod, it is on backwards and that is a Go rod.

Thanks,

Rex

Will it fit in a Go block? If so, probably a Nova of some variety.

The dot under the exhaust tells me a Novarossi and from what I have read the rods from Novarossi are exchangeable with GO.

Looks like the Sirio, it does not have a cast piston so I don't think it's an Rb/Nova.
Thanks guy's!

Good catch Roelof, the dot is a clear Nova indicator. Yeah it looks like the pics of the Sirio but the Sirios don't have the dot.

Measure the rod, if it's the same length as a Nova/Go, it's a Nova. If it's .5mm longer, it's a Sirio.

i have seen novarossi,jp racing and rb sleeves with and without the dimples,some have 1,2 and 3 and some have none.
i believe those dimples have something to do with the production/batch codes as i see no other purpose for them being there.
i am still convinced it is not a novarossi,rb sleeve.
also novarossi use both cnc milled billet and microcasted pistons.

I thought possibly a Axe Rossi, they have big bypass ports.
