figured it was a solas,but whats the meaning on the #s as far as pitch 18 .5?

15/18? but if impros reworked it,it should be engraved somewhere.

i had impros repitch a 13/17 concord to a 13/15 and it wasnt ingraved on the prop. I just dont get the .5 part?

 

[restosud]

they should engrave the new pitch everytime.
all the props i've seen out of their shop has been like that.
