Curious Underfloor Marking? - Mick Hobday - 24-03-2022 During the restoration of my 1932 Four Seat Tourer I found this triangular plate tucked away, spot welded under the transmission tunnel, just about under where the rear seat cushion rests.  There ought to be a reason for it to be there, but what?  Has anyone seen similar plates attached?  I'm wondering if a variety of shapes were used in order to identify the fabricator for quality control or bonus/pay accounting, somewhat  similar to medieval masons' marks.  Any ideas?     RE: Curious Underfloor Marking? - Dave Mann - 25-03-2022     I've got two under the rear floor of our RN, one between the diff and spare wheel and one hiding above the torque tube. RE: Curious Underfloor Marking? - Colin Morgan - 25-03-2022 Is there a hole on the other side that this covers? RE: Curious Underfloor Marking? - Mick Hobday - 25-03-2022 Colin, excellent question!  There's a 1/4" hole, now neatly covered by the triangle.  See top view attached. Dave - my car is one of the first with rear petrol tank, so exactly where your rearward triangle is located I have the large hole provided to access the tank sender unit. Must dash - I have a few more rivets to count... RE: Curious Underfloor Marking? - Andrew Fallon - 25-03-2022 Super picture Dave!
