Nope. The DLC/SLC was their first CPU as far as I am aware. Maybe you're thinking of their 8087 and 80C87 clones, which apparently existed at some point but maybe not as a consumer product.
The CCCCyrix logo appears to have been phased out in 1990. I think the reason you've never seen it is because prior before 1991 386s were just really damn expensive and rare, and not every 386 back then would have had an FPU either. They were produced in very small numbers in comparison to their later 387+ core FPUs. I think pretty much all of the CCCCyrix chips had gold tops, except for the SX FPUs which of course used PLCC.
Try to find a Cyrix chip with an 88 or 89 datecode. I can't.
