      Things are not always as they seem...... The Big Bertha hill climber is a nice piece indeed, but it's not quite
      what the seller claims. If you look through the pictures, you will find this shot, of Bill Altman astride a 45 " OHV Super X, not the Big Bertha, which is a 61" pocket valve. And now, the rest of the story........ The Pickers acquired the motor and had it for sale at Davenport some years ago. I looked it over closely, because it's a very rare engine. At the time, it did have the engraved timing cover. Someone bought the engine and fitted it into a beat up SX hill climb chassis. There are a mix of parts thrown in there, such as the Indian rear wheel and brake, HD handlebar controls and hardware store oil and gas line fittings. There are signs of some pretty good "antiquing as well. So, is it really Altman's bike? Not likely, though the engine may very well be.

      The type M 61" cylinders were introduced in 1920 as the new improved big valve cylinders for the 61" Big X. In 1929, Joe Petralli was working on the 45" OHV motors with Arthur Lemon when he fitted the 61" M cylinders to the SX bottom end and used 61" Big X flywheels and rods to make a 61" SX motor, the Big Bertha. The seller claims this is 1 of only 4 made. I know of at least 5 factory machines. This particular motor is interesting in that it has the later style timing cover and oil delivery setup. This came out on the 45" OHV hill climbers in later 1929 and used on late 30 and into 31 SX street machines. I've spoken with the seller, who won't share with me the serial #, which would really help clear up the question , "Is this a real factory Big Bertha, or a privateer motor , of which there are a few floating around?"

      Very interesting machine, but not really what it's claimed to be......

        The 1915 Harley Model K is also advertised wrong, It is a model E single speed twin street bike not a stripped stock racer, Big difference in value
