OK after a little research I've found out why some of these Razors have a different look.
It was due to different retailers (ie. Bunnings) as they wanted there own look.That's why Bunnings can offer the 10% off any stocked item due to no one being able to have the same item.I'm just not sure where my Blue cowled 2 stroke came from as I haven't seen many with the blue cowl and black air box.
I am going to restore these 2 mowers,not that the 4 stroke will need much work but I still want them to look like they came right out of the box.
So I found these side covers as they both have various amounts of wear.

I can't get a lot of stuff for them.Like the top cover for the handles where it joins the base.I can get grey ones but not blue.Also the mulch plug I can only get that in black,but for the razor they were blue.I will have to get some hub caps for the 4 stroke though all 4 have been rubbed up the side of the garden beds.

Here for a good time,not a long time.
