This is a replica of the BSA/Triumph oil in frame toolkit. I have never seen an original. I bought this from Lowbrow Customs. The tubular "box wrench" was supposed to be 9/16" & 5/8", but instead is 13/16" and 7/8", making the spark plug wrench redundant. The slender ring 1/2" wrench fits the cylinder base nuts. Not sure what they had in mind with the tire valve stem tool, but it was part of the original toolkit. Perhaps to let the air out of your buddy's tires!
