Two very different techs. Which handle with which razor?

I bought two Techs today. Got therm in a lot with a Schick Krona. All 3 for $20.
The first was a Ball End Tech.



The other looks just like a Bakelite handled Barbasol, but it has a Tech head identical to the Ball End, and says Gillette with the diamond on the end of the handle.



Both are definitely user grade, but I have a problem.
I took them both apart and soaked them to clean them up.
The problem is that I did not pay attention to which head came from which razor.
One of them had a C1 date code, the other W3. No biggie, really, but I'd like to get them back on the right handles. Anyone know which goes where, or alternatively, between what period in time the ball end tech was produced(or the bakelite handled one)?
Note: pics are after initial clean up, and after I got the baseplates confused.

The bakelite is for the newer model.

Thanks!

The bakelite handle goes with the W head.

That metal knob Krona looks nice too. Underrated if you ask me. Love my Krona. Love my techs more though

Actually, it's the reverse. The W is a 1951 and matches the Bakelite handle. The newer razor, the C, is a 1957 and goes with the ball end handle. The heads, BTW, are identical, so it won't matter for shaving purposes, but for originality that's the match.

Have fun.
