Unidentified SL tower finds
This page covers unidentified SL tower pylon finds from sources not acceptable as outbound links on the series pages; in most cases these towers are out of reach for replacement photography.

Baby PL16
Line tower like a small PL16, but the transposition tower is the same general design as that of K1373 double circuit. The double earthwire crossarms are PL4-style but wider than normal. The voltage rating is unclear; known examples are insulated to 33 kV but the towers look like they have sufficient clearance for 66 kV. The design is very similar to Blaw Knox K9906 which is a 66 kV type.
