I have had a couple of McMillan 'Fibregrain' stocks over the years, they really look like a nice piece of timber but I do like the marble pattern that you have gone for. JC
The McSwirly was the only option at the time of order, I have heard much about the 'Fibregrain Stocks' but it seems that McM don't do them anymore, which is much lamented in the USA by all accounts. The McWoody pattern and colour mix seems to be the heir to Fibregrain, which means that everyone turns out marginally different.
