Hmmm....3Fi...Ponders*Clink clank rattle rattle,Fizzle...I have one of these,show me a picture please Mr Davis.Since ive next to zero interest in any mower after 1960 (other than two SB 35s)..Yes yes Stone me now,Im sure ive just Blasphemed...(But just to clarify its only my taste and I respect everyones choice in what they love)You may resume Stoning now!!!lols.Ok,So The funny thing is I binned it just days ago,but lucky Im lazy and never bothered to walk the workshop bin to the main,You might be a lucky boy...and also a SB 45? I have one here,dont know what year it is and i think its kinda hideous,always pictured reel mowers as something edward scissorhands would have used if he never had scissors....Yes Ive blashemed again,may the mower gods strike me down...lols.If your interested lets talk a trade sometime,and a pic of this 3fi and see if is the same as mine,I actually thought someone put a later spindle slide in the 3f it was in...and btw it was actually in the early circlip style carby:)If its the same and you want it...It yours:)
