Who can identify these IBM laptop?

I'm an IBM laptop collector from China.
It's a small part of my IBM laptop collectibles.
I put some pics here to see how many people know these type :lol:

Thinkpad 850 or RS/6000 860. These are the only PowerPC Thinkpads I know; besides, the curved chassis is distinctive.
Planned Purchase: T480s i5-8350 FHD Touch
Impulse Buy: Thinkpad not named for safety reasons :lol:

First one is PS/55 5535S which might be only available in east Asia. You can find a lot in Asian market.
Second one should be IBM PS/Note N45 SL, which is in fact a Zenith (maybe the MastersPORT 386SL)
The "too large" picture is shown as the 860, rare one.
The last one is an interesting, long-forgotten IBM PCradio.

PowerPC ThinkPad includes at least four models: ThinkPad 800/820/850/860. besides, there's a RS/6000 N40 in IBM laptop series, not ThinkPad labeled.
