Google comes through again! "Distributor Cam Grease". Mallory 26015, but Summit has "not available" on that page. EuroMotoelectrics has it CS-Lube. ACDelco U1901, Bosch P905536, and of course, AMAZON has several brands, too. MACS, SuperLube, Std Ignition, and others. Some in a tube and others in a single use packet.
This forgotten maintenance item is still out there, more choices than I ever suspected. Amazon might be the best shot, but the one time I wanted to buy something from them, I couldn't get past the sign-up for Amazon Prime to get to the checkout page! Their price for the larger tube is about $13.00, which will last many lifetimes, but adding the cost of Amazon Prime to that would make it far too expensive, IF you're not already in Amazon Prime. Might be listed as "Distributor Point Grease", too?
So, look around on the supplier websites for the best deal. I'd recommend Summit, but not sure if they're going to get any more in. Check and see.
