Hi oz, Welcome here, congrats you found yourself a little treasure there.Don't want to tell you how to suck eggs but remember it is a 2 stroke, wouldn't want to see it destroyed by you not knowing, many of these have been destroyed this way and still do to this day.
Still got another 50 years left in it and bases are pretty easy to come across, just don't be fooled into big ebay prices, just keep an eye out for one to bob up for $15/20. Be careful using it because the name says it all, a "toecutter" Only other disadvantage is no catcher. In the fifties people were just grateful to be able to cut the grass and raking it up afterwards was far easier than pushing an old Ogden cylinder mower around that wouldn't cut the grass if it was 3 inches high
