Letchworth. There was a BorgWarner plant built there in '55. The '68- 03 '71 510s used Borg Warner 35 automatics, some made in Letchworth. Makes sense that they were also used on the Roadster too. I've never seen one for sure so thanks for this.  

That oil pan is the RL411 sedan/station wagon oil pan. The transmission is the BW M series, not the US Muncie Indiana unit.  The generator is that, a generator not an alternator.  This is likely a cobbled together hybrid of roadster and sedan parts.  I would view it as a parts unit not a rebuild unit. Early block, doesn't have the add-on bosses for the automatic transmission feature shift mechanism.

I find myself wondering if the BW transmission is off an Austin ?

Right I should have checked. This is the same engine/trans in ]2eDeYe's 411 wagon. Letchworth is in Britain and supplied transmissions for all of Europe. Almost for sure Austins had them. Nissan got into bed with Austin in the mid '50s and built them under license for Japan.

Are you building the Hillman Husky?  There is at least one sitting in a private junkyard here in Denver.  I thought about grabbing it a few years ago, but didn't!  It was still there 4 mo's ago............
