Hi Stationary.Have been away on a Brisbane mower collection safari,so I've missed new posts.Wow what a good find.What you have there is defiantly a Model 2 and you found original badge on it.Good work.Let me know when you take the badge off I can tell you if it is a Model 1 or 2 badge.They were different.I'd say a 2 thought.Yes these Tin wheels are original.Don't know why they were called tin there made of steel,but anyway.All Model 1's and 2's came with these wheels.Plastic wheels didn't come in until the model 2A 1957-58,and ran right through to the Sheerline in 1960.The only thing I can see missing there is a cover that went on top of the flywheel.That was there for two reasons one to make it a little more attractive and two protect the fins.Properly manly from body parts such as fingers.OK then enjoy the restore just keep us updated as you go along.Looks like you scored some fairly good rubber on those wheels.Just be careful not to tear them off the wheels there are no new ones available.If you run into problems I do know a way to replace them.They not quite the same but it's close enough.I can't quite see but are the washers holding the wheels on welded?If so the best way to remove is careful grind them away.Good luck.Any problems you only need to ask.Enjoy.
