Mcyl sight glass

Has anyone had experience buying M/cyl sight glasses. From down here in Oz the only suppliers I can find are in the US. If anyone has had a good experience with a supplier could you forward details please?

I bought a couple of these item no.322441298248
Easy as to fit although I pushed the glass in with a vise rather than hammering it in.
If you need some and they won’t ship to OZ let me know and I will sort something out
