Crank no start, no spark

You can check the coil. Bump the dist so points are open. Connect an alligator clip jumper to coil NEG. "Rig" a test gap to the coil tower. ALWAYS test with a solid core wire, not a radio/ resistor wire. For spark testing you don't need spark plug wire, any low voltage wire will do if you "space" it in air. Turn key to run. With test gap in place, tap your alligator clip lead to ground repeatedly. If condenser and coil are good, and coil is getting power, you should get a spark.

It is better to jump full battery to coil+ for this test. If no or poor spark, suspect condenser before the coil Do not leave key "on" and allow coil to heat up/ overheat. That can damage coils and points

To double check coil power, clip coil NEG to ground. With key "in run" coil PLUS should run anywhere from 6--10V The variation is due to type of coil, to value of ballast, and how good/ charge level of battery

If you suspect condenser and you have ANY condenser out of any battery type igntion (some magneto condernsers will work but might be wrong value (capacitance) Unhook old condenser before trying another. If the old one is "leaky" it will gum up the works, electrically speaking. The only GOOD way to check caps, most guys don't have. You need a Real By Gawd old school condenser/ capacitor tester WITH A HI VOLTAGE LEAKAGE test.

Otherwise, all you can do is buy a couple of spares and hope one of 'em is OK

"New" does not mean "working." Remember that with ANY replacement part.
