As I'm sure you know, George, the Victrola Doctor, will be able to help you with the correct tone arm since he has a huge stock of parts. BTW, he'll probably have the correct door knobs too.
I wish I could provide you with a picture of the correct part, but like your machine, mine also came with the wrong arm. I bought my machine as a complete working Victrola, but soon discovered that not all of my records would play on my Consolette. The tone arm would skip & stick on certain 78s. Why? After getting help here on this board, I found out my back bracket was too tall. Then after that new part arrived I discovered the tone arm was too big.

By then the springs needed a good cleaning too since they were thumping. Springs are easy to clean (cleaned the Colony springs), & most of you guys wouldn't have given up, but since I'm not mechanically inclined & most importantly I was completely frustrated I did.

I sold my Consolette (& 2 other machines) this spring to a person here in my town.
