Thanks Rob, if you go here, there are close ups of that mirror you are interested in, shows the mounting foot in detail which will be a give away
The red circled one is definitely of a MKVII, presumably the MKV is the same
I have people interested in it, one is a MK4 owner, another has a XK120, who sent me dimensions…this one seems slightly larger than the dimensions in Urs book
The one you identified as XK120, is shown on Internet/Amazon as variously correct for XK120/140/150.
I assume there were variations in the exactly correct mirror over the duration of those models
I will send you a PM about something else (which you will like), but also to test whether PMs are working, which they seemed not to be, if you could reply that would be appreciated
never sent so many PMs in all my time on JL and the PM system appeared to decide to croak today !
