Kamet made that style and they are the T310 series. The MTAC seems like a AVX part number but it's hard to tell at times. Could also be a Mallory number too. I'm looking for my old part cataloge for the late 70-80 when I find it I think it will help.
Last year I unreeled 6 pallet of them and filled an entire Gaylord full of them.
