I decided to repeat this interesting item from the old forums:
I have a set of records which theoretically should not exist.
Back in the 1930s and 1940s, record companies actually offered their multi-record sets in three different sequences:
Manual sequence, for those with single players.
Drop-automaitc sequence, for those with drop-type record changers. These changers do not reverse the order of the stack as they go through it.
Slide-automatic sequence, for those with Capehart and throwoff record changers. These changers DO reverse the order of the stack as they go through it.
The slide-automatic changer disappeared very quickly after World War II began, because this kind of changer broke the records made of substitute materials during the war. People who had them usually disconnected the change mechanism.
So the slide-automatic sequence also disappeared very quickly. By the time the LP and 45 appeared on the market, there were no players or records offered in slide-automatic sequence.
A couple of multispeed players appeared in the mid to late 1950s or early 1960s which used slide-automatic sequence (probably unintentional, due to the mistake of not noticing that the changer reversed the stack until it was too late to change it). They were the Fisher Lincoln 70 and the Thorens TD-224.
So how come I have a set of 45 rpm records issued in slide-automatic sequence? Even more puzzling is the fact that none of the changers listed above which could use this sequence were yet in production when this record set came out.
The set is:
"I Love"
Monty Kelly and his Orchestra
Essex Records ES-EXP-111
To play the songs in the same order as on the 10'' LP version (and as listed on the jacket), the records must be played in slide-automatic order. This means reversing the order of the records by hand as you turn the stack over.
Even weirder is that the recording catalog numbers on the labels have you playing the second sides of the discs first, but still in slide-automatic order.
The 78 version of the same album was in manual sequence.
Something tells me someone wasn't thinking at the time they made this.
