48 Fleetline 216 engine w/ oddball filter housing

Here's what I know so far-
It has WBG stamped in two places- stands for "WBG Oil clarifier"
The Napa gold 1006 and 1100 elements are a shade too wide od. (Napa ones are 4 1/8" or 4 3/16"). Mine is 4" od. The height will be right at 5" tall.
It is blue and has a giant wing nut on top for quick cover removal and is very heavily built. Is mounted with u-bolts and a plate to the manifold just like many I/ve seen on other 216's.
Effen file upload fail on pics. Any help much appreciated -freezerburn

 

It's not one of those that takes a roll of T.P., is it? (Not trying to be funny- I've really heard of those!)

 

Hey 500, no offense taken but no, it takes a filter of it's own design and I found a couple! -freezerburn
