A quick google and these appear like road cranks to me.
I've recently got and fitted the truativ omniums which are mid(ish) priced track cranks with external bb.
They seem nice and stiff so far, were easy to fit and spin nicely, the chainline seems fine with both on one and bontrager track hubs (so I assume 42mm) but without measuring it the q factor is a lot bigger than my campag record pista cranks.
