I find for my Mark V judging guide I need to provide some easy identifiers of rear windows for the judges.
Width and height measured on the outer edge of the chrome with a pocket tape, general shape and number of screws inside should be enough.
My current belief is that three different windows were used at one time or another in Mark V DHC tops. Two were also used for XK120 OTS.
BD.1369 is an oval with 20 screws, also used on early XK120 OTS.
BD.4405 is an oval with 16 screws, also used on later XK120 OTS.
So, is anyone in a position to check my screw counts, and get some height and width measurements with a tape on either of these?
