[xk] Alloy XK120 Window

(XK-SS) #1

The rigid window and 3 latches in the 1949/50 alloy car’s to
top are different from the ones in the steel cars.
I have the latches but no windows.
Can anyone supply accurate drawings or a photo with scale of th
of the original window.

Thanks

I have an original rear glass that I could trace out for y
you and should have the correct height measurement some p
place as it sits lower than one would imagine. This window i
is the same as the MKIV DHC if you have someone local. Do y
you have a sample of the original domed nut that holds the f
frames together?

Hi Mike

This is not an answer to your question, but here are some notes re alloy car
rear windows:

XK120 - PB60/79A - This was different for the alloy and steel cars. The
alloy cars had BD 1369 backlight with glass only listed. There was no
listing for rubber buffers.
All the steel cars used the same BD 4405 (assembly) and glass BD 8070, with
4 rubber buffers on the frame (no. 2179). The assembly was the same as for
the XK140 RS (see PB152).
Bruce Carnachan’s notes: early cars had glass rear window, later cars had
plex-glass [sic].
670178 - Jag World Jul Aug 94, page 44 photo: caption states that domed
nuts on rear window frame are chromed, and “shape of frame is slightly
squarer than later cars”. Looking at the photo, it is not 100% clear
whether the frame is slightly squarer, but it might be.
Material: glass or perspex? Jim Canedy says re Mk V DHC that his rear
window was actually glass.

I will send some pics off list and copy Jim K.
Again, they are of course not a direct answer to your question and indeed
with one car you will have to form a view as to whether these alloy cars are
themselves original!

The best tip was the Mk IV DHC rear window. I don’t have a Mk IV spare parts
book but the MK V book I have shows the “Backlight Complete” at page 114 as
part no. BD4094 which is of course different from either XK120 “assembly”
part number.

A pic of the MK IV rear window at page 100 of the Service Manual I have is
not all that helpful but does seem to show the rather squared off corners
mentioned.

Back in 2013 on pre-xk I was looking for information on the
Mark V DHC, and we had some discussion of the rear windows
on all models of the era. They are called ‘‘Backlight’’ by the
way.

http://forums.jag-lovers.org/av.php?1631299o17

Here are all the backlights of the era listed in the parts
catalogues.
BD.1369 is for Mark IV
BD.4094 is for Mark V
BD.1369 is for XK120 OTS alloy
BD.4405 is for XK120 OTS steel & XK140 OTS
BD.6760 is for XK120 DHC

We didn’t reach any absolutely definite conclusions about
Mark V, just that they may have used different backlights at
various times.
But it seems logical that for alloy 120 they could have been
using up excess BD.1369’s as they apparently did with Mark V’s.–

Hi Mike

I have now found this message:

Georg Doenni Feb 99: We had ten XK 120 Aluminium rear hood windows made
even with glass inset and not perspex. Nobody is interested in it. And these
are only a few original parts we manufacture.

I will email Georg for you. He would like a customer who needs two of them!

Kind regards,

John: I am looking for a rear hood window for my 1950 Alloy XK120 (670173). Are there still any available that you know of? Is Georg Doenni still around? Thanks, Phil Cassou

Phil,
I had a few of the early style chromed surrounds with dome nuts made for 670088 and 670110 a couple of years ago.
I sold some but may still have one.
Will check for you when I get back to CA.

Hello; I am very late to this posting but also have a need for a complete rear window, for a Mark 4 DHC. The window that came with the Car was totally non standard and I would like to return the Car back to original when the hood is replaced. Can anyone help please . Many thanks in anticipation. Owen.

If you can confirm part number BD1369 is the one you need, I may still have one surround with nuts but no glass.
