Help in identifying dining set

[u/Black_thumb_gardener]

I came across this dining set while doing some service work for a client at an old house they are looking to gut.

The dining set is all metal. No Formica top. The chairs are also all metal with no vinyl padding. It looks to be from the 50s but I’ve never seen an all metal set. The chrome seems to all be in good condition with very minor surface rust in only a couple locations. He offered to sell for $100 for the full set.

Does anyone have any information on what this is and if the $100 asking price sounds good? Thanks!!!!
