Tuning Machine

[Liam Irwin]

Good Day All, 
I recently purchased a 2009 Vigier Excalibur Supra. The seller had replaced the tuning machine for the low e string with a Sperzel Drop-Tuning contraption. This mechanism works poorly and needs to be tossed. Can someone help me with finding a replacement tuning machine to match the originals? The other 5 work flawlessly and are in good shape. I don't need a whole new set; I need only the one.
Thanks in advance,
Liam

We will open a Vigier parts shop soon, you may find it there.
You did not keep the original machine head??

I am not the original owner; I bought it recently on Reverb in it's current condition. The seller (on Reverb) did not disclose that he had switched it out and did not include the original.
