Transformer Model Kits

Does anyone remember in the 80s, there were these Chinese model kits (you could buy them in Chinatown)

They were basically a kit where you put together a Transformer (I assume these were bootleged from the actual model). Plus it came with a stick of delicious orange gum

If anyone has any idea on what this toy series was called or where I can just look at pictures of the boxes or completed models of them, please let me know in this thread
