You need to remove a tuner and measure the diameter of the hole (inside the bushing) with a digital caliper. You may also want to remove the bushing to measure the actual diameter of the hole through the wood. Then go on a website such as stewmac.com that sells vintage-style tuners to check their dimensions.
Adapter bushings are available to accommodate different size headstock holes and tuner stringpost diameters.
It isn't possible to say with certainty what your guitar has now, as tuners get changed fairly often.
