Looks to be a very nice 32 Long you have there. It would have been shipped in 1899 as far as I can tell, so just missed antique status. You can always get a letter to accurately determine the exact date. Grips should not be a big deal to find. Check out ebay and Gunbroker. Someone here should be able to tell you what other models had that grip style if you want to replace them. I can't tell but are there patent dates on the cylinder?
