Hi everyone i am looking for help with the value of an HW55 with tyrolean stock that i am looking to sell. This gun has not fired 20 pellets, have had this in my collection for many years, 177 calibre serial number 960256. This gun is virtually as new, there are 3 very small marks on stock, bluing as new. Any help with valuation would be greatly appreciated. Can email pics if requested, thanks bob
