Hi all! I have a Elna Primula 410 that I overtightened the needle bar crank rod and cracked the metal. Elna and other online suppliers do not have this part. It's a Japanese manufacture from the 70's, and the model is pretty uncommon, but it's a good machine and I don't want to give up on it. Does anyone have any spare parts lying around, or maybe a machine (if really cheap)?

Part name: Needle bar crank rod
Hosel's part #: 1047
Tavaro's part #: 395'047-56

Thanks in advance!
