Thanks for the comments guys !
So, working my way through my list of jobs, I'd been looking for a suitable interior rearview mirror.
Porsche had obviously raided the parts bins for the original cars & installed a 356A/B mirror so I set out to find a good used one with some 'patina' &, being a cheapskate, i didn't want to pay 'top dollar' ...
Since I knew I could buy a new reasonable quality repro version for ~ $100 + shipping (which, if it came to it, I could buy & 'distress' suitably) I used this as my ceiling when looking for a used mirror ...
After a number of false starts, I tracked a suitable one down in the US which had been laying in a box on a shelf for the past 30 yrs, having been removed from a crashed car in the late '70's ..... a 904 !
Obviously, I have no way of substantiating this (& what does it matter anyway) but the seller did have some more 904 parts & was well-known in Porsche racing circles back 'in the day' so I was happy to pay his asking price ............... $20 + $15 shipping !!!
I also bought a few more bits from him ...
Here's the mirror as received:

A pleasing result !
