A friend of mine who makes pistol grips has made a number of the Walther hardwood cocking aids for the Walther LP53 air pistol

These replicate the original and are made in beech or walnut. They include the metal guide that locates down the barrel.
Price is £12 posted

Does anyone need one, if so please just post on here and I will ask him to make some. When they are available(in 2 or 3 weeks)I will then pm buyers his address to order them. Please indicate whether you want beech or walnut
