In terms of old stations or former departments in Clackamas County, the only ones that come to mind are from Milwaukie Fire Department. I don't remember station numbers, but I do remember where they were located.
The north most station was at the corner of SE Harvey and SE 40th Ave. They had two engines, Engine 51 and Engine 52, and BLS Rescue 56, in addition to some older fire apparatus in storage. The building is now either privately owned, or owned by the City of Milwaukie's Public Works.
The former Downtown station is at City Hall, and held one engine and the chief's car. Main St. and SE Harrison is where it's located.
If I recall correctly, CCFD's Station 4 on Lake Road was part of Milwaukie fire department, until lack of funding shut it down in the 90's.
Also, Buck Ambulance was the primary transport service covering the city of Milwaukie. They were stationed out of their office at SE 23rd and SE Washington, across from Milwaukie High School, until AMR gobbled them up.
Clackamas had a station at King Road and SE Fuller at one point, but once Station 1 was built, they moved out of it. That's all I know about old stations or departments. If you're interested in more historical info, you might want to go to the Ledding Library in Milwaukie. They have a lot of articles on the fire service in the area since the early 1900s.
As for mikepdx's info:
The East Division was dismantled sometime after TVF&R's contract with Oregon City ran out in 2002 or 2003 (I can't remember for sure). At the time, CCFD Station 15 (John Adams) was TVF&R Station 50, and CCFD Station 16 (Hilltop) was TVF&R Station 54.
I made some adjustments to the following to reflect current apparatus:

Something I failed to mention while I was spewing data...
The Oregon Department of Geology did a statewide assessment of all the police, fire, school, and EOC's in every county. This is quite the list, and although I've found they skipped over a station or two here and there, it's accurate with most departments.
