[78-L] 10" Par-O-Ket?

[Glenn Longwell]

I've asked this question before but some new potential evidence has shown up for me to ask again.  As you may or may not know Par-O-Ket is a U.S. 7" vertical cut record from 1916-1918.  The more common catalog number series starts at 2 (maybe 1 but I have never seen anything showing it) and runs to 125 (last number announced in Talking Machine World).  In June of 1917 the only listing I've seen of the rarer 500 series showed up and numbers there ranged from 509 to 530.  In May of 1917 they announced in the Talking Machine World that they would soon manufacture a 10" disc because of increased demand from jobbers to sell a 10" record for under 75 cents. The last listing given is December 1917 and by May 1918 they were bankrupt and their assets were being sold off - along with 30,000 records. I had yet to ever see anything else about the 10" record and no one has admitted to ever seeing one.

Why am I bringing this up again?  I finally came across my first 500 series records and they showed up today.  I checked Ty's site again to see what he had listed for the 500 series.  New to me was he has number 530 as being 10."  The record listing of June 1917 makes no mention of this and my highest number record is 524 and it's a 7" record.

So I ask again - has anyone ever seen one?  Ty - where does the information come from?  Was it a physical example?

Thanks,
Glenn
