Your splendid mirror is one of 250 made and numbered by my pal in Glasgow.(From my design).
I still have the original prototype mirror, which is a one-off, and is slightly different from the other 250 (Plus it is not numbered).
They were made for and distributed by a Mr. P. Kane
I was well chuffed with them at the time, So, much so, that i made a similar one for our 2016 SC Win.
