This telephone is based on the Dutch T65. The T65 was developed by Krone, in cooperation with PTT (and commisioned by PTT).
Krone later designed a different body shell and handset for this Phone, resulting in the FTA 67.2 (other specimen are marked FTA 67.1). Almost all the components are identical: circuit board, dial, hookswitch, ringer, etc?
The Phone was made in grey, orange salmon, olive green, turqoise and transparant.
The 67 in the name presumably stands for 1967 as the year of introduction.
