Even though Northern Electric had access to the Armstrong Regenerative License from at least 1923 on the company chose to market the companies first broadcast receiver as a Non-regenerative set. The R-1 pictured in the November 1st, 1922 Radio Bulletin No. 1000 didn't have an external method for adding a plate variometer to provide regeneration. Later models had two binding posts in the upper RH corner to allow the addition of the Northern Electric R-20 Variometer to provide regeneration. 

This picture shows the R-20 Variometer hooked up to the R-1 Receiver.
