Help ID-ing Tama Steel Piccolo


Just took in a Tama steel piccolo on repair at the store, and I've never seen anything like it. It's a 3x14" Tama Steel Piccolo. It has a the Tama tag and serial on it (105986). I cannot find anything like it online, and it's got a lug holder pattern I have never seen. It's an off-set with lugs coming out for top and bottom of the snare on the same holder. I realize I'm being unclear, so I supplied a (cell phone quality) picture of them as well.

Anyone got any background on this snare? I'm needing to order new parts for it and have no idea where to start. Thanks!
