That's really good to know, thank you. Those elbow patches have really thrown me, not gonna lie. I'm guessing they're stock but I just can't see Lewis Leathers putting out something that looks like that even way back then and even with the inside tagCan't speak for the authenticity of that jacket but I've had a genuine Lewis in that blue leather from the same time period and it was lightweight but stiff, I don't think it was sheep, more like a lightweight horse or cow, anyway it was same colour and leather to yours. There are a lot of bespoke Lewis Leather racing suits that are very different from the stock jackets, the racing suits would sometimes come with different or no patches externally. , if I had to hazard a guess, yours is the top half of a woman's suit or a bespoke item but could still be a lewis
