I could stretch it even further to new-built Moderus Alfa if I wanted to really even though it's not based on Konstal 105Na(which was of course in turn based on Konstal 13N outside of the body shell, and Konstal 13N was quite literally a copy of Tatra T1, while this one was built on PCC license) outside of the body shell being inspired by it (asymmetric door layout, 4th door of unmodernised 105N(a)s missing)
