From Dillon website
The "C" designation indicates a significant design change. The upper link arm pivot pins are now threaded in place, and have a grease groove around the pin that connects with a lube hole on the end of the pin. You can use a needle fitting on a grease gun to lubricate the upper pivot pins now.

So in this picture i see no grease fitting so this must be a B model.

Download user manual and parts breakdown shows the grease fitting. Can't see it in any picture of press. My pic hosting site down so I can't post picture of it

I will include a picture of my RL550B. The pins at the top of the swing arms, solid on left, hollow on right. You press looks like it has had little use. I also have a much older RL550, and had an upper swing arm gall. Not hard to take apart and fix, but lube is your friend.
