I had a quick look at some of the 336's on eBay and from what I can see, the direct wired ones also have the deep flanges on the drivers which I believed was always a later change.
What is curious is that your 336 is direct wired and looks to have the smaller flanges on the drivers. The question to ask is which year did Gilbert change from small flanged drivers to the deep/larger type?
I suspect that there has to be some documentation around when Gilbert went to direct wiring and flange changes which will explain some of these anomalies floating about.
Also, does anyone have a spare tender for a 336, I picked up an engine about a year ago but someone had taken the tender.
Lastly, what is the reason for Northern tenders commanding high prices as a separate item? Is it because of the earlier ones suffering frame rot or people wanting them for pre-war O gauge Northerns?
