You should be abal to source a bearing of the correct size given that number and make. A quality bearing supplier will know what is needed. If you have the old one so much the better for size comparison. Worse case scenario is size the inner and outer race sizes and depth with a vernier gauge and take those to the bearing outlet.
I've got the measurements just like you said. The critical feature of this bearing is it has a 2mm deep notch on one shoulder of the outer race where the bearing holder seats. It's 30x72x19mm: Id, od, thickness. Don't think anyone makes such a bearing. And the ones on Ebay are expensive and some even with rust 🙄
