Hi Geoff, Your machine is an early 14" Scott Bonnar Model 45 and was manufactured sometime between 1968 and 1974. Unfortunately it is impossible to date the machine accurately as Scott Bonnar did not include a manufacturing date as part of the serial number.
The reason I say it is an early model is that is has the early SB logo on the handle cover, and the screws on the chain case cover are vertical, whereas the later models had horizontal screws...and of course, the Kirby Lauson HK engine which was made under licence for Tecumseh USA. The later SB Model 45 had a 3 HP Briggs and Stratton fitted.
Re your decision to restore, I think you should consider the following;
The machine is all complete and as Grumpy has pointed out, the cylinder reel looks as if its never been sharpened and has lots of 'meat' left.This indicates it may not have done a lot of work.
Although the catcher appears to be not original (maybe homemade?)it is serviceable and second-hand originals can be sourced if you wish.
In my opinion, I think it could be restored very successfully.
To give you some perspective, these machines in their last configuration, were the Rover Model 45 and sold for $1895.00
All parts are still readily available, including chain case covers, even a brand new bare chassis....Replacement decals are now available as well.
We have many Scotty 45 owners active on the forum that will assist you if you decide to restore your machine.
You may consider as the first thing to obtain a Scott Bonnar Model 45 Parts list and User Manual through the "Parts and Manuals" area on the main forum. (Just look a the very first post in any topic on the main forum page for the instructions "How to Access Parts and Manuals) Subscription will be required, but will be invaluable during re-assembly.
Just as an example, here is a link to some pics that were posted by Stu45. He has restored a 17" Scotty and is awaiting a new engine as his Kirby Tecumseh has had its chips! Click
