jacketing color scheme

I have a 520 built in 53 or 55. I also have the jacketing which i have just put on all the screw holes line up but the side and back panels are a very dark regal blue yet the front and top is a very light blue like seen in the tutorial in this forum. Did these jackets come with different colors or is this a sign of retro work on this unit like the ash pan guide was burnt out with a torch for some reason.

E.F.M. had a two tone paint scheme in the early years SCRAPPER

Be thankful you didn't get the model with racing stripes.

thank you scrapper . Having visited to your shop and seen all the stuff you have on hand I beleive you 100 percent. I will factor that into the history of the 520 I have . I could not imagine someone in Slatington, springing to buynew jacketing because they where discolered or slightly rusted.
