I had doubt it's the original hub as I could find any wordings on the hub. I'm worried previous owner might have changed the hub. The nuts have no holes on it comparing to video i saw on YT. Can someone tell from these photo if it's genuine?

I can’t tell you exactly what hub it is, but it’s certainly not a stock, as of 2020, Sturmey Archer. If it’s a 2020, then it’s almost exactly the same age as mine, and it looks nothing like that.
Given the large number of modifications I can see, even at a casual glance, I wouldn’t assume anything to be stock aside from the frame 😅
From my knowledge this hub was the one brompton has prior to 2014 when they introduces the sturmey archer hub
Brompton used sram for a period when sturmey archer had supply issues. This puts your bike probably pre 2009. Still, it looks in good condition, so I wouldn’t be too hard on yourself, enjoy the bike. Here is a video showing how to adjust your hub: [https://www.youtube.com/watch?v=DX6KfC9uOUU](https://www.youtube.com/watch?v=DX6KfC9uOUU)
This is thr SRAM 3 speed around 2004 model.
Also the crank set indicates this is an older frame with some upgrades to it.
SRAM are reliable hubs assuming they are still in good (working) condition i.e. no dragging, good shift etc.
Your bike is pre 2013 based on the crankset you got scammed OP.
my knowledge is pretty limited but Sturmey Archer didn’t release any 3×2 hub to open market except for when Brompton ‘took over’ their designer, redesigned the hub and reproduced the hub, with tweaked configuration to enable 2 cogs to fit on the hub body with wider gear range. it is made in Taiwan under licensed from SA under new ownership (Sunrace).
as a gap filler during this transition period, Brompton commisioned SRAM to supply OEM 3×2 hubs with Sachs hardware, which SRAM kinda newly acquired too. the hub is alright, but it is a pretty closed ratios hub, so u don’t get the benefit of wide-range gearing on 6s C-Line with Brompton BWR (wide range) hub. the main issue with SRAM hub is repairability, if it goes bust there’s no parts from Brompton anymore. Cogs are still source-able, but not as easy as standard Brompton parts.
