Greetings all,
I collect pre independence French colonial stamps,I have however found in my collection a stamp of Cameroun I will guess at a date of 1970s,I have no post independence data,it is 100f satellite monitoring station zamengoe with over print in red in english and French which reads;' to the welfare of the families of martyrs and freedom fighters of Palestine',I can find no info about this stamp,thanks in advance,Ian

bonjour jan,
it took some searching just now, but i located your stamp in the 2007 scott catalog. it is sc. #635 valued at $ .90 mint, .40 used u.s. dollars. there is no illustration that accompanies the stamp, but the overprint is on cameroun #617 radar station, 100 fr. as you have described. thanks for my mental exercise today.

amities,
cajunsr.
