Yeah I think sizing was a little more loosey-goosey back then - bike fitting has probably become a lot more technical these days. I think the best you can do is look at the top tube & seat tube lengths and make the best guestimate - espeically if you know about what size you should be.
I was riding a 52 Specialized Roubaix (2016), and the numbers were similar enough to the size 52 on the R1000. I think I probably should have a 50 for the R1000, but the odds of me finding one still in existence is near zero, so I'll make a 52 fit, like I did with the R300.
