Hi I see from your list you have no mention of SANGLAS a motorcycle made in Spain up to about 1984 , These pictures are of a Sanglas 400 Electrico used by the Irish Army between 1974 and 1989, a 400 cc 4 stroke Single with Kick and Electric Start

Pictures taken by myself

You’re right Philip. It’s a new brand to me. It’s not often that I get to see on I literally knew nothing about She’s a beauty. Interesting design though and clean as a whistle. Thanks much!
