Question about U47 clone resistors

Hi gang, I'm building a U47 clone and across the 'net I've seen some interesting looking resistors. I'm attaching a pic of one by Telefunken USA and one by Peluso. What ARE those orange/beige looking resistors? I can see "DALE" on one, so obviously they must be Vishay/Dale, but are they metal film, carbon comp, carbon film, wire wound...? I just didn't have the patience to troll through endless product pages on Mouser/Digikey.

Also, why would one choose these huge mamas? Aside from curbside appeal?

Thanks any help!

They are most likely metal film resistors, but searching the number codes printed on the resistor with google/mouser should reveal their true nature.

Dale or IRC metal film judging from appearance, is my guess.

Thank-you gents! Much obliged!
