The first image of post #433 is clearly taken long before 1895.
Footbridges over the klongs [might be a clue] are quite evident in this particular pic, as road bridges weren't developed along this klong triangle until mid 1880s.
This is many, in a series, of well known time framed photos at the conjunction of Klongs Saen Saeb, Banglamphu and Maha Nak.....all shot from circa 1875-1880 obviously taken from Phu Khao Thong [Golden Mount] at Wat Saket looking across to the Fort Mahakan community

Sir Henry Norman didn't make his way to Siam until the late 1890s.

Nonetheless, keep up the good work.
Cheers, Nat!
