Has anyone noticed a tube video on F book of a Russian museum Matchless X3 /1931 ,...the bike has a set of uncommon girder forks ...not Matchless ,IMHO ,but maybe some continental type.........four straight tubes ,with a bridge across the top for top pivot and also headlight mount.............Im sure Ive seen similar on one of the 1930s tiddlers ,maybe a Wolf 250? imported to UK from Germany?
