HELP: Need to identify these toy parts please

Non-transformer related toy parts I'm trying to figure out the identity of, were received in a bulk lot of toy parts from the 1980s. Any assistance appreciated. Parts are for sale:

2 x red plastic seats with peg in the base for attaching to a surface. No distinguishing markings.

1 x black plastic shield-like items with peg on the back, and unique sticker applied to front. No distinguishing markings.

P.S. My first post here in around 2 years!

The shield looks about the right shape to be from a Gundam. How big are they?
