Standard Soundbox (Victor?) on eBay

[alang]

There is a "Standard Soundbox, Philadelphia" on eBay right now. The seller "phonodoll" claims that this is a rare early 1900 Soundbox that came on Victor A, B and C machines of that time. I have never heard of this reproducer and cannot find it in LftD or the Victor Data Book, only the "New Century" and "Concert". To me it looks to have many similarities to an early Exhibition, so I don't understand why Victor would have built the "Concert" afterwards. Since phonodoll is an experienced phonograph seller I do not doubt his claim, I would just like to learn more about this reproducer - even though I won't be able to afford it.

Thanks
Andreas
