I purchased a 500DM a short time ago. The wall side (623D) modular receptacle appeared to be original to the phone; however, a part of the receptacle was broken allowing the receptacle to move in the opening. I found the "Old Phone Shop" thanks to some ad hoc 'Google Fu'... I ordered this as a 'spare' and also ordered the pair (handset and wall receptacles). All three came in the gray plastic color shown in the picture. The originals were brown... so, that leaves me with my only suggestion - source both and let the customer choose the color. Regardless, I replaced both (so they would match) and both fit perfectly. Very happy to have a working rotary dial phone! I am using vultr as a cloud hosted PBX provider with ClearlyIP SIP trunk. A Grandstream HT801 (ATA) is configured for rotary dial and sends and receives calls... GREAT project. So much fun... hope more people bring these things back to life.

Mark answered my question quickly to help me order the right part for my Dad's old rotary desk phone. The part arrived the next week and Dad installed it and it's working again!

I really appreciate being able to order a replacement jack for our rotary phone. Dropped the phone on the floor and was glad to be able to fix it thanks to this part! Plus the Old Phone Shop is quick & efficient, a pleasure to do business with!

A nice jack at a reasonable price.

My old rotary phone was dropped right on the jack side, breaking the jack. Could not determine how to glue it so I did an internet search for parts. I queried the proprietor for the correct part number, which he answered promptly; it was a stock item so I ordered it. It was shipped promptly and I received it via US mail a few days later. I was then able to replace the broken jack with the new one by matching the connections, however the wire color codes were different than what was in my phone. It worked fine and I am satisfied that this phone will work for another 50 years!

exact replacement for the 500's equipped already with a modular end, spade connectors are exact, no fitment issues. Great for a retrofit if you want to make your older 500 easy to use. Modification to the body needed for older 500.

The phone jack was delivered quickly, and fits like a glove, I will do business here again.
