Ian, no harm, no foul, the matter is trivial to anyone but a Scott Bonnar historian. You might have had a machine that had been retrofitted with an 11 cubic inch engine. A lot of SB45s have been re-engined by now (including Deejay's own beloved example, which now has a Honda G100 engine).
Joe and Gadge, I didn't say it but I meant in the core SB45 period that Ian's mowers came from: 1968-71 for the one piece deck, and around mid to latish 1970s for the collectible SB-made two piece deck machines. I'm not certain there weren't 11 cubic inch horizontal crankshaft 4 hp engines in that core time, I just haven't heard of one personally.
