What type of baseboard is this?

Can you tell from external appearances what types of hydronic baseboard radiators I’m looking at? I suspect it’s a mix of cast-iron and slant-fin, based on how recently the area was renovated.
Sorry for the lousy photos. I’ll hopefully get in for better photos sometime soon.

Yes, I agree. Photos 1, 3, and 5 show cast iron radiators. Burnham still makes a similar product. The other two are fin-tube baseboards, technically convectors.
