G-Grandfather Clark (restore and date help please)

[Neale1961]

I would love some tidy up and repair of damage to this photo of my G-Grandfather please. NO COLOUR THANKS.
I know the portrait was taken in the 1880s, but any help to refine this date is welcome. My research puts Kyles photographer at this 29 Newmarket St Address, in Ayr in the 1880s. John was born 1860 and his family were from Troon. In the 1881 census John is living in Ayr, working as a tailor. There is no wedding ring, so it is before 1888 when he married and then moved to Glasgow. It could be an engagement photo (aged about 27), but he has rather a “baby face” and youthful looking hands - so perhaps he is early 20s. Opinions sought. Is it possible to refine the date by his clothes?

My try.

All you can tell by his clothing is that he's not someone who gets
his hands dirty for a living.
You can see he's wearing a morning jacket this being typical daywear
for clerks, bank tellers & professionals.
I would agree he looks early 20's so mid-late decade is about as close
as you will get.
Can we see the back?

Japeflakes, Peter and John - Thank you so much for the restores - excellent work!
Jim - thanks for the dating information. So we will guess at his age and date the photo ca.1885.
Photo back posted.
