maybe someone can identify this font. this is a font from an ad from the 70s. lots of similar fonts but i can't seem to find the exact font. very similar to Pentaprism 5, but the "S" is different. i don't think its custom.

can anyone help? much appreciated

Here is my suggestion, the A and R are fitting, the S in upper case isn't, but look at the lower case s, maybe that was used..

thats it! thank you so much!

My pleasure!
