Mr. Nice seeds has a NL#1 X NL#5 , that may be the closest you get to an original NL#1. I had the original NL#5 , bought direct from Holland ( even though the envelope had a California post mark} before the internet, Mr Nice's Ortega was the closest to it I've found.
Sorry, too old and paranoid for pics, but I had 7 females and all but one were winners, they basically grew themselves, these I will run again, they were a bargain.
