Date of NYC Humber

[NYCHumber]

anyone know a year for this Humber? The clues are the wrap around seat tube stays, oil plug for lube in the bottom bracket. Clamp on down tube for shifters. Cable hook on bottom bracket for front derailleur. Gusset bolt hole for generator on the front fork. Pin style cranks…
Any help would be appreciated

I couldn’t find anything on that site to match. I will look at the rear hub and on the inside of the fork tube and check back in. Thanks
