Webley also made a run of Vulcan MK2s with a choice of walnut tyrolean or sporter walnut stocks. These had a distinctive arrow shaped area of checkering on the fore end. The shape of the pistol grip is very pronounced, these stocks were not custom stock cs500/600s. I think they also did editions of the tracker with these stocks.

I have a factory tyrolean vulcan which came from The Mart in Lowestoft in about 1986.
