I have acquired a Generous Quantity (+200) male 11-pin "octal" (yes yes, I know...) male plugs.
These are 'chassis mount' type plugs and have waffle-shaped retaining rings with them, but no shells. They are keyed between pins 1 and 11. They are NOS and have never been soldered or used.
Free for postage from zip 89706 (Carson City, NV), one to "a handful". Let's be reasonable, here folks... ;} Drop me a line OFF-LIST if any interest. Cross-post this to other BA Restoration lists as you see fit. Cheers John KB6SCO
