I have checked with Walther, and there will be a factory Walther service team based in the LRC at Bisley to cover the Junior international Aug 8th to 10th, and the small bore meeting the following week 10th to 19th.
Don't expect them to have parts for classics though, they are there to support current Walther shooters with air and small bore guns.
Have Fun
