I wear 8 in C&J 337, AS 109, AS 99 and in Carmina Rain. 7.5 in AS 87.
Finnishing "issues" is sole edge color on the suede here and there, as when buying Meermin at Classic level.
With regards to sole it is not about imperfections/errors, it is just that the way it is done it looks thicker/bulkier mid foot than under the front part. Heel (height) and sole is lacking a bit of refinement for a dress shoe but would be quite okay on a double soled country longwing IMO.
Only a matter of taste.
From what you're saying, you're size is UK8=US8.5=EU41.5. (AS 87 Last is a very generous country boot Last so you have rightly sized down in it by half.)
