As sort of a last resort, I called Source. I told him what I was looking for. He says they have the ROL gaskets. But the gaskets are now white without the red embossing the ROLs have/had. I ask what is stamped on them and he says Corteco. But, supposedly the same makeup/composition. He also says they are 4.480 bore, .044 compressed, where the ROLs were 4.380 bore. .045 compressed.

But, the website shows them as being .051 thick.

So WTH??
