I don't own the PP2 buck. It was loaned to me for all of 2016 with a bit of overlap from late 2015 and into early 2017. After that it was returned to its current owner. Additionally, the other pages of the linked site contains images of some of the unaltered casts that were made in 2015 from a new mould - minus the skirt. Those pictures are helpful because the casts are one uniform colour and this makes it easier to see the properties of the buck, both good and bad.
Those pages also show the alterations that I made to a copy of the buck to make it into a useable cast for painting. Those changes will likely be similar to the things that Lee Malone did to create his 'Malone Fett' helmets. The casts, and therefore the buck, share some of the issues that the GM had [although not all] but generally of a less egregious nature.
