Soldering iron was WTCP-N, and the tips indeed have 6, 7, and 8 stamped
at the back end. They were my Father's.
Funny thing is, I thought the iron was like screwdriver bit holder.
Every time tip makes contact, there was "click" inside. I thought
something was loose. So, I tried to fix it and ended up breaking both
the tip holder and the main station.
Now that I've seen the inside, I don't like this type. Too many moving
parts. I'm currently using simple cheap 40W iron with screw-on tip.

While cleaning up, I found soldering tips for Weller soldering iron.
Those tips appear to be for the old TCP series Weller irons. If they
have a number, such as 6, 7 or 8 stamped on the back end, then they
are. Temperature is controlled by the tips themselves. The slug at the
back changes from magnetic to non-magnetic when it reaches its curie
temperature. This controls a magnetically activated switch in the
iron's shaft to maintain the temperature. The number on the tip
indicates its nominal operating temperature 6=600 degrees Fahrenheit ,
7=700 F, 8=800F, etc.
These tips won't work in (newer) Weller irons that aren't designed to
work this way.
I have several TCP type Weller irons. I take them if nobody else wants them.
