Might have been incorrect in a post I replied to in part numbers on a Century radial Leko. Had a bad inventory noting about fixtures related to notes. Below is my revised notes and photos of the fixture in question. Sorry for confusion in the case on a radial fixture with a modern G-9.5 bi-pin lamp base. Photos show this radial Leko is a Centurey/Strand #2321 are factory and in fact the case for the paint used and in general modification to the lamp cap so as to house a G-9.5 base instead of a P-28s base.
