This CRT has identical technical data and dimensions compared with 3WP1.
It is only the Phosphor that makes the difference between various models:

3WP1 = green fluorescence / green phosphorescence / medium persistence
3WP2 = greenish-yellow fluorescence / greenish-yellow phosphorescence / long persistence
3WP11 = blue fluorescence / blue phosphorescence / short persistence
