There's nothing there that jumps out at me as being an indicator as to whether it's English or Italian. If it's just an axle it probably doesn't matter.

A 70 is an Italian SHELL width which has different threading on the cups than the more common BSA.
There's also a 5mm difference between the bearing races on the spindle.
See this- Scroll down a bit to the chart.

With a name like "Tien Hsin", I doubt it's other than BSA.
What's the difference in offsets between the 2 ends?
What do you REALLY want to know?
