Okuda Hand Inoculator wanted

I would like to say hello to everyone, my name is Sergio, I just joined today and have liked reading all the valuable information everyone shares here and continues to post.I am in the planning phase of outdoor shiitake log cultivation and was looking to see if anyone out there has or knows of anyone selling a used or refurbished Okuda Hand Inoculator.I've attached a photo of the specific tool. This tool would help me a lot in savings when it comes to innoculation labor for myself. Thank you in advance for reading this and I hope someone out there does as this would be a gamechanger since I will be doing most of the innoculations alone.
