Growing Perimeter Layer Thickness

Calling all experienced printers.

I am trying to print the 3DLabPrint P51 Mustang and need help. After a couple of weeks of trial and error I have managed to work through all but one of the issues that I have been having with this print.

Background:
Rostock Max V2
.35mm Nozzle
PLA
Layer thickness set to .25mm
I have owned this printer for a few years now but haven't used it much.

The issue:
The outer shell of this print is a single thin wall. I have the layer width set at .42mm. The actual width of each layer varies between .29mm at the start of the layer and consistently grows to .53mm at the end. It doesn't matter where the start/stop position is located around the perimeter, the result is the same.

Anyone have a cure for this behavior? Need more info?

Thanks
Bary
