This Simplex 4903 that I have in my collection is what I believe is a misprint or a prototype of some kind. It has the model of 4903-9136. I’ll post pictures in the future, but does anyone have an explanation for it? Thx
I don’t see it in the Simplex Model checker, but here’s another thread with someone else with the same model: About my simplex 4903-9136
That’s actually my post I made a few years ago on it. I did find information of it though. It was replaced by the 4903-9147. Here’s additional information. It’s 15CD, a vertical mounted variant, currently disassembled in terms of the speaker and strobe, and has an A at the end of the 521-780, assuming it’s an ID of some kind
