Columbia Grafonola question

[DanP58]

Good Evening,
I recently acquired a Columbia Grafanola E-2 I think from research I did. After removing the crank, motorboard and tonearm for transporting I found 2 cup like washers in the compartment with the horn. I didn’t hear anything fall while I dismantled it. Can someone tell me if they are part of this machine or some random piece that fell in there . Since there’s 2 I’m thinking someone might have worked on this machine and left them off for some reason
Thanks
Dan

Well I got a few different answers as to what these are.
• oiler cap for turntable spindle usually with felt washer
•oiler cap for spring barrel usually with felt washer
•support for motorboard screws

I like the "oil cap" suggestions.
