Picked these up somewhere along the way and haven't used them yet so it's time to let them back in the wild.
When I got them I drilled the 1" side to accommodate the 2 hole Altec bolt pattern. This was professionally done on a Bridgeport mill by a tool maker (Me).
Flange Dia on the 1" side is 3.9" with the Altec 2 hole bolt pattern and another bolt pattern with 3X 1/4" holes drilled on a 2-1/4" bolt circle.
Flange Dia. on the 2" side is 4.7" with 4X tapped holes on a 4" bolt circle. Holes are tapped either 1/4" fine thread or 6mm. To lazy to check at the moment but can do if it's important. There is a lot of room to add your own bolt pattern if your so inclined.
Overall length is 3" so the expansion rate (cone angle) is not as abrupt as most adapters I've seen. Heavy cast aluminum construction but there is no indication of the manufacture on them. Probably had stickers at one point.
Asking 50 bucks plus shipping from NJ.
