Here's a pic of my drum with "original" calf heads. These ARE the original calf heads. Period correct would be if i bought these heads yesterday and put them on the drum. These heads have been on this drum since the 1920's. And even if they were put on the drum just yesterday they're still the original heads. They have the cow stamp. This gives new meaning to the abbreviation, pc - period correct. Let's all be a bit more pc -period correct and stop using the word "original" Those lugs on your snare that you thought were original? Well, you can't say that anymore. Why? Well, someone took offense. From now on you gotta say they're period correct. :P
