Do you know what size they are and do you want wood or carbon fiber blades??If you do not know the size maybe I can find the size somewhere on the net.

There is a possibility that they will be the same size as my Freya 60 around a 700mm blade and if that is the case you may want to go with mavrikk blades from Heliprozs because a carbon fiber blade of that size from say MAH will cost you around $125.00 and Mavrikk 700 blades will be around $65.00 to $70.00 for carbon fiber,I use 700 mavrikk on my Freya.I also found this while searching
