So does it have the fish scaler? - Pretty unusual in an 84mm - Otherwise I agree with Boonies
As to your question:
Regular 84mm scales should fit - You can try ebay or searching online - But 84mm scales are not so common as 91mm for replacement.
So you could buy any current 84mm model and use those scales (fitting may depending on the age) - I guess the Waiter is the cheapest
Ooops - Just seen Boonies comment about the 84mm scales being available
Although as Boonie says if you do have a Small Master Craftsman - It's a more uncommon model - So you may want to keep as is.
If you just like users - Go for it!!
PS. You'll find you get a more useful response if you give your post a more meaningful title.
Make it summarise what you are asking and action orientated!! eg.
Where can i get replacement scales for an old 83mm (or 84mm) five layet Angler? Just the name of a model does not tell us much!
