Unknown "Philly" Dairy ???

Just picked up 4 circa 1930's milk bottles from Philadelphia dairy's that are no longer. I'm familiar with 3 of the bottles, but this one is unfamiliar to me possibly because I'm assuming it was a Philly dairy. The bottle is 9 1/2" tall & reads One Quart Liquid, then in a circle Sebold & Kumbach, S & K, 2951 No. Orianna St. Underneath that L. C. CO. While it doesn't say Philadelphia on the bottle the address is good there. I've come up empty on my research. I would appreciate any info I can get on it.
