The two badges have been known to fetch a lot more than the £35 'Buy it Now' price, although recent prices have been lower, but I would have thought the whole lot was well worth the asking price.
Just one point to correct, and that is the paper voucher for the 'Marksman Badge', which is for the second version of the round badge and not the 'Flying Bullet' as shown. The voucher for this badge was square in shape, and mentions a 'Flying Bullet' not a 'Marksman' Badge
