I never thought I’d say this, but I now have enough. Navy Type 49121-A plugs. 

15 extras are now available for $5 ea plus postage

These are on 1’ or 2’ long RG-8 patch cords with a connector on each end. If you want an odd number, I’ll cut the cord. 

They look like this

I also have 18 Navy Type 49120 panel mount jacks for the same price. They look like the ones in this box. 

Will deliver to Dayton/Xenia. Act today because I am leaving Tuesday and will probably take them to sell there unless they are spoken for. 

I’ll donate these free to needy museum ships.
