Peerless 16687 & 7142 Transformer Identification

[number9]

I could really use some help with identification of the these two Peerless models. Friend found them on some estate sale shelf. Transformers are removed from original chassis with original long plastic insulation leads. 16687 is about the size of an EL-84 OP transformer, flat chassis mount, open frame, no drawn steel end bells with Peerless decal. The 7142 is flat chassis mount, drawn steel end bells, Peerless decal, about 150-200 mA. I contacted Mike at Magnequest and he thought the numbers were familiar but was unable to offer a solid identification from any prints in his files. Any Altec or Peerless collectors recognize these model from a chassis in their collection?

Hello, I have seen the transformers you have in an Altec 351C 50 watt amplifier. The 7142 is the power transformer and the 16687 is the output transformer.
