What do you guys think.

Looking for approximate year that it was changed over.

Hello Oldmics

Looking at the Library Catalogs in looks like the early sixties and it seems to be crossover model dependent as the older ones keep the screws but as you see newer ones come into the catalogs they all seem to be the push pins.

Until 1983, when my 4343's was build, they was still push style, so i doubt the Paragon was equipped with anything else.

The early Paragons that use the N 400 network are screw attacthment style.

I was not specifically looking about information about Paragons but thanks for your input. :)

What I am trying to figure is when they changed the N 2400 network from older style screw attachments to the newer compression style.

The N 2400 had a really long run of use.

Maybe Harvey would know.

I believe Robh3606 is correct in his assumption that it was changed sometime in the early 60s.

Oldmics/N2400s in both styles of attachments :blink:
