I thank xiphophilos for the fair and equitable solution to this situation. Also for fixbutte's and slholzer's input and knowledge about these matters. This is an example of just how interesting, (and dare I say....exciting) record collecting really is.
For the most part, I'm with xiphophilos and fixbutte on this. A mislabeled disc is still a variant of the standard disc. Notations of known mislabelings should be included, with photos where possible, in the entry for the standard disc. This should include not only labels used incorrectly on the standard disc, but labels from the standard incorrectly used on other discs.
One case, however, might require an exception. If both sides of a disc have been mislabeled, and neither side bears a label that would identify the disc by its proper company and catalogue number, a separate entry may be necessary to allow anyone who actually has the disc to look it up. I don't believe I have ever encountered such a case, but then, I might not know it if I had.
Errors putting together two sides that don't belong together are also known, but considerably rarer than mislabelings, because they require the wrong metal parts to be installed on the presses. That was probably an engineer's job, and likely done under closer supervision by higher plant management than was the case with the labeling process. Whether properly labeled or not, these really are a different coupling and probably ought to be accorded a separate entry once discovered. It would surprise me if such an error did not usually involve one of the sides being mislabeled enough to trigger the kind of cross-reference referred to above.
I own a few mislabeled discs myself. Usually, the label of one side is attached to both sides. Sometimes, the label of a completely different disc is attached, as in your case where the runout number tells the true story.
Do these factory errors make for a true variant (i.e., different coupling) that needs to be recorded separately? I personally don't think so. I'd mention it in the Notes under the actual release, like fixbutte. In fact, I have now combined both entries.
To answer your question fixbutte, .... yes. (and) I would imagine that Victor 17677 would be easy to find on E-bay. Again, I was hesitant to enter this display, but I did it to prove a point about the importance of label photos.
This is interesting. Do you really have the correctly labeled Victor 17677and this mislabeled copy? In fact, it must have been a big seller because several copies of the correct version are available on the web.
No matter, I think this one should not have an extra entry because it may have been a singular mislabeled copy and does not contain what the labels show. I'd prefer the B-side images to be moved to the correct copy, denoted as an aberration.
I have thoughtfully provided a close up shot of the label on the B side. Please note the matrix number stamped under the label. I contacted the L.O.C. about this disc, and they told me that it was either a mis-pressing, a mis-labeling, or both. Upon playing the disc on side B, I discovered it was a mis-labeling. I was hesitant about entering this disc. There could easily have been a claim that I submitted the images from two different discs, and faked an error. However the photos don't lie, and this is why a photo for an entered disc is so important here. The song played back was "That Moaning Saxophone Rag", the label doesn't say that.
