Rim lock ?
They are, I believe, Excel rims. No reason to believe they are not stock. One hole has the tube stem, the other is plugged. One is a few inches from the other, both on the flat. Weasel noticed it and pointed it out. He asked me and I had to confess ignorance. Anyone?
2nd hole is for a Rim Lock to prevent the tyre and inner tube from slipping on the rim and ripping the valve off when running low pressures 👍

I'm very familiar with rim locks Purple, but I've always mounted them 180 degrees from the valve stem...can't say why, that's just how I was taught. Think that's it eh? Seems too close to the valve stem...but what do I know, maybe close is better in terms of protecting the stem.
Research says the new conventional wisdom is close to the stem and in front of it as considering the direction of spin...which means that puppy is right where it ought to be. Thanks for clearing it up guys. I guess the days of drilling your own hole directly across from the valve stem are way past. The shroud of vintage darkness has parted for me.
