What's the story on this? 45 rpm but a normal size spindle hole, with the ability to punch out a normal 45 size hole.
I believe I only own two like that, one from New Zealand (Hogsnort Rupert's Original Flagon Band before it was released by WB in North America) in about 1971 and the other a 12" 45 I bought in England in the mid-1980s.
This looks like the usual size 45 pressed in Canada.
