I am offering for sale a parts kit for a Grandpa Nambu Holster stock. A near-perfect reproduction stock modeled from an original. Made to exacting specifications to look and function just as the original. Cherry wood body and lid, carefully selected. The telescoping neck locks in the full forward and retracted position. All metal and wood components are provided to produce a stock like ones that have sold for $4000.00. All that is needed is some fitting, finishing, and assembly. The finished one shown is available for $3750.00 but is not included in this auction. Please pass this information on to any and all your friends who may be interested in Nambu Pistols. If you have any questions please give me a call at 262-628-4669 after 5:30 PM CST or contact me a Heidiho1@charter,net..
I don't know the gentleman, nor do I have a Grandpa (or Papa) Nambu that it would attach to...
...But it is interesting...
