They McEwan's and Belhaven products in the use are not 60 shilling examples.
Despite what the BJCP guidelines suggest, 60 shilling is not a smaller version of 80 shilling (or vice versa). Belhaven 60/- is darker in color than Belhaven 80/- (exported as Belhaven Scottish Ale) and is in fact too dark for the style despite being the first listed classic example.
The 2008 BJCP subcategories 9a-9c are good at describing US home brewed and commercially brewed Scottish Ales and a pretty poor job of describing beer in Scotland. I hope this is one of the areas in which the 2014 guidelines will contain corrections as divorcing the guidelines from reality to cater to the local audience only works for a local organization.
