Thank you all for your kind remarks. The bonnet, BoldHighlander, was new but old stock when I bought it. I don't know the maker and the colour, in reality, is a little darker than in the picture (where it looks more like RAF blue). The badge is bracken, the plant badge of Clan Donnachaidh (the Robertsons), although this one is a silver alloy rather than its botanical original. Well spotted!
