Surprise find: Mechs!

My housekeeper was cleaning my hobby storeroom yesterday and accidentally spilled the contents of a plastic container. She gathered up the bits that had fallen out and showed them to me as she was worried that she may have lost some parts of what seemed like a bunch of unassembled models. I was pleasantly surprised at her find -- plastic mechs I had purchased sometime in the 80's! I h ad assembled these for some battletech games with my cousin but had forgotten about them when my wife and I moved houses.

Some of the units had broken parts but I managed to salvage three complete models. The others could be repaired with some putty and wire -- if I could find some of the left legs:)

We picked these up during a trip to Manila's Chinatown and they came in sprues packed in a transparent tube with four models a tube. Along with these, we also got some Not-Macross Valkyries, Battloids, Gerwalks, Warhammers and Archers in brightly colored plastic.

I remember using these with 1/72 figures but they seem ok too with 2t5mm and 28mm figs.

Any idea what models these are? Am guessing knock-off Heavy Gear. Comments welcome:)
