Unidentified astromech droid series

An unknown series of Astromech droid that was in service on several planets throughout the galaxy. On the mining colony of Tyne's Horky an orange and red colored unit was being sold at auction outside of Doodnik's Café, and a purple and gray colored unit was present on Biitu as part of the Great Heep's Droid harem.
==Behind the scenes==
The head shape of these droids appears to be somewhat similar to that of the R4-series agromech droid, but this model has more of a neck and appears to be taller.
