I don't mean to promote anyone's business here. May I post a hard to find resource in the spirit of helping vintage guitar enthusiasts pursue their passion?
Just learned from my guitar collector buddy (a very picky guy with 104 axes) there's a highly recommended DeArmond & Rickenbacher vintage pickups specialist. My friend used this guy and praises his work and customer service. Check out the website:

Hope this is helpful to folks. If this post crosses the line, I'd understand a decision to delete it.
