The Little Record With The Big (Or Small) Hole

I found this sleeve for a 7" record the other day, and thought it was sorta interesting. For years I thought all 7" 45 rpm records had a big hole in the center. Then I found some with a little hole, but they all played at 33 rpm. Then I found a few records from the UK that had a center you could pop out if you wanted a big hole, or leave the center in for a small hole. I never knew such a think had ever existed here in the US, but here's a bit of proof. The little doodles to the left and right of the center hole explain how to adapt the record to your turntables requirements. You never know what's out there until you find it. 'O.C. 45' they call it, Optional Center, from your friends at Capitol Records.

so if the hole size between 45s and 33s confuses you ... what are your thoughts on 78s??

78s use the same size center hole as 33s. I have some old Seeburg Background Music System 16-2/3 RPM records somewhere that have something like a 2 or 2-1/2" thru-hole, though. Now those are really confusing!
