XK 120 Backlight, early 1950 OTS


Need help identifying this backlight, it measures outside 24"x5" has 14 screw holes.
Bought it for my early 1950 OTS not certain it’s correct.
Any thoughts on this is appreciated.

Hi Frank

Welcome to the forum.

People with better knowledge than me will be along shortly but my understanding is that backlight is not correct for a 1950 XK120.

In the first instance it appears to me the ends are too square though perhaps that would be acceptable if your car is pre 670185 LHD / 660059 RHD - part number BD.1369.

Even if it is for one of those vehicles according to “Jaguar XK120 Explored” 2019 edition p.352 part BD.1369 is only 22" wide whereas the backlight for a Mk IV or Mk V is noted as 24 3/4" wide.

Otherwise for cars from 670185 LHD / 660059 RHD the backlight part BD.4405 is noticeably higher and has ends that are a very clear radius. This part also is noted as 22" in “Jaguar XK120 Explored”.

“Jaguar XK120 - The Anatomy of a Cult Object Volume 2” pp.100-101 has some instructive pictures of various early XK120s which lead me to think most early 1950 cars will be using BD.4405.

I had a bit of a look on XKData and 670263, 670266, 670268, 670288 among other 1950 cars seem to have BD.4405 installed.

You might find J.8 spare parts catalogue useful too, pp 60 & 79A.

Good luck.

MKIV and MKV is 24 3/4 inches x 5 inches
early XK120 is 22 inches wide squared ends like MKIV one shown
late XK120 is 22 inches with half round ends.
XK120- Explored has it all noted page 352

I think my backlight is a BD 1396, I also think that my car is a very early production number, so this may be the appropriate backlight. Thanks guys, appreciate your time and knowledge.



Alloy car backlight BD1369 had studs with hex nuts and glass not plexiglass.
I have a spare.

If yours is 24inches wide it is the wrong one it should only be 22 inches wide.
What is the chassis number of your car?

I am not sure of chassis number. I am in Florida right now, I will check it when I get home and let you know. It should be no later than next week.
Appreciate your assistance.

It would be nice to get a really definitive identification on all these backlights as used on Jaguars of this period.
BD.1369
BD.4094
BD.4405
BD.6760
general shape, pictures, measurements, number of screws

Seems we’ve had this conversation before …

Rob when you do the definitive piece on rear backlights in XK’s and Jaguars ie MKIV an XK120DHC.
Please note the very earliest alloy cars ie 660002 the backlight was a piece of glass I have the original from this car and it has a aircraft type metal locknuts holding it together
