[NJARC] Seeking National HRO Tube shields and top covers:

[Joe Cro]

Greetings All,
                   Would anyone have an early (big pin type) tube shields and their respective top covers for an early National HRO receiver they'd like to sell?

I just acquired a tubeless and tube shieldless early HRO ( production date: March 1936) that I'd like to put back together. I have the tubes, but no shields. 

Any leads will be greatfully appreciated.

Mod-U-Later,
                  Joe Cro N3IBX
