The A15 standard also could have been for smooth bars or deformed bars depending on the era so you should confirm they are deformed.

Depending on the work you are doing, it probably also is a good idea to take some steel coupons of the reinforcing to confirm properties. ASCE 41 has recommendations on how many coupons to take, etc.
