Sling swivels for 1st year Remington model 30 restoration

[knuck39]

I have a 1st year manufactured Remington model 30 I would like to bring back to “life”. It has a finger grooved stock that will work but if anyone has one for sale that is in better condition I’m extremely interested.
The main reason why I’m posting is I’m missing the sling swivels (front and back). I know they take the hook loop type, but the front one seems to be an odd bird that screws into a ring on the barrel. Any info on where I can get these items and what exactly the swivels look like would be much appreciated.
Thank you very much.
