There is no way of knowing when a production run is going to be limited. I ordered three Nightwatch NSX53 3 x XHP 50.2 at the end of 2019, and only one was obtainable, on Jan. 2020. I kept my order open, and another new one miraculously materialized the day before Christmas, eleven months later.
One of my favorite high quality, low budget screamers.
I think making flashlights is at least a full time job for Simon. I am not sure whether he has any employees.
Nightwatch, to my knowledge, has a full time job at day time. He only assembles his flashlights at night.
