Specific Doll Help identifying Switch head

Uhui:R maybe? I have one too, although mine is heavily modded now. Heres a picture of a blank one.

Interesting! My Uhui has a "19" inside his head, so if they numbered their releases, something around that time? They did had CoAs back then. Ryun:R also looks kinda similar...

 

I feel the eyes might be a big larger than Uhui:R. The large, round eyes, M-shaped mouth and deep philtrum make me think it might be Ajeong:C or Yiho.
Here's some Dollyteria listings for comparison:
Ajeong:C
SWITCH/AJEONG CLOSER ver. S-25-11-02-496-GN-ZS
SWITCH/AJEONG CLOSER ver./BJD　球体関節人形 I-25-10-19-205-KD-ZI
Yiho
SWITCH/YIHO　Dollism　Plus　Tokyo　2018/BJD　球体関節人形 A-25-08-20-303-NY-ZA

 

It might not hurt to post this in the main Switch thread as well, since the numbers inside the headcap do correspond to specific sculpts. Case in point my Waseon has 29 inside his headcap, as do other owners Waseons, and my Ajeong C. has 31 inside his.

But, I'm in agreement with Idrisfynn that it's probably Seolrok. The earlobes match pretty closely.

 

I am almost sure thats a SEOLROK. I had one ages ago but hes the one with the nose bump .There is various versions of this sculpt though this one is this version

SEOLROK

Hope it helps
