Not really: Your sentence implies that you know already, that "these combs" are combs after all, the answer can be only yes or no according to the owner.
The given sentence on the other hand is assuming nothing about "these". So the answer could be "No, those are my forks." :-)
To add, in Romanian "are these combs yours" would be "Acești piepteni sunt ai tăi?"
