Was there ever a Neopan 1600 in 120?

I would like a high speed option without pushing and am getting results I like using Neopan 1600 @ 800 in 135 but am still trying to narrow times down on Delta 3200 @1600 using stand development with Rodinal 1:100 + Xtol in a 4+1 ratio (along with ascorbic acid, baking soda and Borax).

So far 20 min and 30 minutes result in gross underdevelopment. I will try 45 and 60 minutes next.

Was there ever Neopan 1600 that existed in 120 format?
