If (big if) you can get to Shanghai, the place to go to see Seagull cameras is the Shanghai Camera History Museum, 300 Anfu Lu (Anfu Road), 3rd floor. Free entry.

The museum is very professionally laid out and I would guess that it must have a webpage, but I can't find it easily with an English language search; perhaps it's only on a Chinese website.
There are a number of interesting things including an old manufacturing workbench with some boxes of Seagull TLR parts, in addtion to all the cameras in display boxes. Much of the display texts are translated into English. There are also some very rare things like examples of the Chinese
Hasselblad and Leica near-copies.
