A up-to-date list of shops that can repair older airguns

I've recently came into possession of an Anschutz 380. All things considered, it's in amazing shape, clean and lightly used. The seals, on the other hand, have not held up well over the last 40 years. I shot one shot before I noticed and haven't touched it since for fear of damaging anything. So, of course, I take to the internet to find someone who could potentially work on it. It's all various forum posts from the early 2000's, and I've only gotten 2 email replies saying no dice... I'd absolutely hate to banish this rifle to the back corner of the safe, so I'd love to find some names and contacts that are in active service.
 
Don't know who you tried so far but might wand to give these guys a call. From a conversation I had with them it seems like they repair and work on some of the older guns.

Baker Airguns Rocks. Give them a try. No affiliation I just know his work and he is a big supporter of local Field Target events in Ohio.
