Ben, check out this eBay seller. I've bought several items from him and have never had trouble. The prices are good as well.
https://myworld.ebay.com/cougarvalleyhwt If you don't see anything you need or want, just search any of the following keywords on eBay search:
- 1a2 key
- 1a2 phone
- 1a2 key system
- western electric phone
- multiline rotary
- rotary office phone
I started off with pretty much exactly what you have now, so feel free to PM me any questions you might have, or check out my website that's in my signature.
Good luck to you!
