Yep, it's a R&P. I've never had one. I'm told you should be careful not to pick up any grease in case you transfer it to an eyepiece glass.
I think the Bintel Crayfords directly replace this R&P (search for threads here on focusser replacement). Buy the 10:1 for only some $20 more, that gives you fine focus. But, as I said, unless this one is wobbling all around the place and cannot be tightened, perhaps spend your money elsewhere for a while.
You cannot always have your computer handy? Recommend that you spend $20-25 on a Planisphere - unless you have memorised the sky!
