[Boatanchors] WTB: National Tube Shields and Bases

[Freeberg, Scott (STP)]

I am still looking to buy some National Tube shields with bases.  These are the styles used with the National SW-5, SW-3, FB-7, early HRO, etc.  Some, like the SW-5, are simply cans with a lid and base, others have the 'lighthouse' cap on the top.  I've got two receiver projects that I'd like to duplicate the original articles.   Do you have a few that you can spare?  
Thanks. 73, Scott WA9WFA
