Getting pretty deep into building my Barth 1/4 scale Waco.... coming along nicely. albeit kind of slow. Currently building the outer wing panels. In the hardware bags for both the upper and lower wings there are 25 (in each bag)small brass nails - parts #137 &237...... can't find any reference to these nails on the plans or in the written instructions. Have several ideas of what they could be used for, but nothing solid. Anyone out there know what these nails intended usage is??

Thanks for iny info you may be able to provide!
