Model 29...Ill check that as its not familiar and ive got every model listed from 58 to 78.

The Rover" reference relates to this Style" being originally a Rover Mower.

SB have just rebadged and renamed it,most likely to fill a gap increase sales by alt means or meet demand.

Anyway its easy enough to service and engine/service parts are still available...still alot of SH parts around to. Like I said previously,Im scrapping an original rover tommorrow identical to yours:)
