OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Walk Behind Lawn Mower Frames Question On Scott Bonnar Cylinder Mowers Scott Bonnar Model 45 - Model Information.

I am putting together a list of Scott Bonnar Model 45 mowers to try to estimate approx date of manafacture, as well as changes made to frames/parts during the manafacturing process. With the model,mower and engine numbers i want to cross referance this with as many mowers as i can, to create a registery so to speak.
If other SB 45 owners wish, could they send me the details of their mowers as well as the date of original purchase if known.

Information i would like is:
Model No. (eg450423)(Some have no model No. on mower)
Mower No. (eg 12345, or 45 12345)
Engine type/HP if original engine(eg Kirby HK25 or B&S 2.5hp)
Engine No. (Kirby have metal tag or plate on housing near starter eg H4-5A W646706)
(B&S have Model Type Code on housing side near petrol tank on early models)
Any other info relating to design changes (eg one piece base, vertical or horizontal bolts on chain drine cover, "SB" decal on handles or "Scott Bonnar" decal, etc.
Any info any one can give me would be greatly appreciated.
There is so little information out there on these mowers in regards to run changes and dates made.
Thanks.
Matt.
