Oliver Superior grain drill identification

[TraderMark]

I picked up an Oliver Superior grain drill today.
I can't find a serial number plate on it anywhere.

I'm confused as to whether it's a model 38 or a model 64.
I've found pictures of this drill saying both.

Can anyone help me identify it from the picture or tell me where
to find the serial number plate?

Thanks,
Mark

Can't help you identify your drill but was wondering if you knew if Oliver bought Superior Seeder.

Sorry Creamer. I don't know much at all about the history of Oliver other than their partnership years ago with Fiat and then the Oliver buy-out by White.
