Hi Guys, The blade was gone before I bought it and the boss had one of the 4 protrusions broken off. For all I know it may not have been a Victa boss and somebody could have replaced the original with the boss I had to get off. The shaft is the same length as another Victa I have with that same engine (but with normal Victa boss/blade). I'll try and dig it out of my garbage bin once the maggots have settled down a bit.
