Not sure what you are asking for. Magnetron is briggs name for their electronic ignition modules. When they first started changing over from points to electronic there was a separate somewhat clear box that slide between the legs of the module, which then goes integrated into the module itself, and since briggs changed supplier of their modules a few years back some of the new modules don't even look like the old ones.
So if you are looking up the module by what Briggs. I am sure what you are receiving is correct for your engine.
