Thanks for reopening this thread so i can extrapolate a little further on the original list by Gadge and with pictures of all bar 2. The Scott Bonnar 97 (1977) and the Small Engines 199 (1990). I'm putting all the mower one's in this reply and the Small Engines in a reply to this post.
Mowers: -Scott Bonnar series (to 1977) number 97 -Rover series (1978) number 99 -Mowers series (1971) number 100 -Rover series (1978) number 101 -Victa series (1974) number 102 -Victa series (1977) number 103 -Victa twin and lightweight series (1977) number 161 -Victa rotary mowers series (1955-81) number 200 -Victa rotary mowers series (1955-84) number 220 -Victa rotary mowers series (1955-87) number 403 -Rover rotary mowers series (1992) number 422 -Victa rotary mowers series (1955-91) number 424
The scientific publications number 100 covers all victa models but is only named "Mowers" on its cover and spine. So technical its a victa workshop manual but it's not officially named VICTA.
PS: I could only collect the one's I have because this thread gave me a starting point of what names and numbers of the manuals to look for. So a massive thanks to Gadge for his original first post on this thread that led me to find manuals like Small Engines 112 that I didn't even know existed.
