The modern brand name of the makers of these liners is "Parker Hale". Not sure if they still exist, but they were around a few years ago. They did lots of low-end conversion work on ex-military guns after WWII, but seem to have supplied liners to "The Trade" for many years, since you find these liners on some fairly high-end rifles. I think they had some relationship with the Midland brand as well.
One common confusion on these relined rifles is that some of them were marked .220". So they sometimes get offered as .220 Swifts.... Gun Fun, as the Celestial menu hath it (or is it just ballistic chop suey?).
I think you'll find your Greener a very classy little .22 once you find out what brand it really likes to eat. They can be picky, even with a great bore.
