House was built in the early 1970s, so I presume this Sears Intercom is from around the same time. I have already removed the interior intercom and replaced it with a wall tablet. I am hoping to replace the exterior speaker with a video doorbell, but I can’t figure out how to remove it. It’s 5" x 3" and has no visible screws or recessed holes. I haven’t been able to find anything similar to this online. Any thoughts?

You guys were right. Mesh screen was just held in by side tabs. This allowed me to see the metal back plating. No screws actually hold the plastic cover on though. I just used the metal back plate as leverage to walk the plastic cover forward, pulling out the two corner plastic push-in pins. The screws seen are for holding the metal back plate in. I appreciate the suggestions and help, thank you!
Keep it, it’s kinda cool and period correct
