Putting a bike together out of bits in my shed ,just because I can.
I have a crank from 1994 ,it has 5 arms and the bolt holes are about 52mm apart.
Is there a narrow wide ring that will fit?
Assuming the distance between bolts is actually 55.2, corresponding to a 94mm BCD, yes: http://www.wolftoothcomponents.com/products/94-bcd-for-5-arm-cranks

Beaten to it ^
Probably 94 PCD: http://www.sheldonbrown.com/cribsheet-bcd.html
Someone was developing a NW ring and separate spider / carrier system but not sure its for sale yet - can't remember who the company was.
Wolf Tooth do 94 BCD 5-arm rings - I've not seen any others:
