Hi Jamie, Sorry it has taken so long to reply, but I'm just getting back into the swing of things after my hols in Brisvegas.
To your question, Your machine should be a 16" Model 33 manufactured at the earliest in 1960. The numbers on the brass data plate after the model number:(33) are the mower number which do
not run necessarily sequencially, but
could mean that your machine is Number 989 in the production run. You cannot, unfortunately, date
any Scott Bonnar
exactly by the data plate information.
Hoping this helps,
