You could get version history metadata from Lists.asmx.

Sample code:

var web = clientContext.Web;
                List spList = clientContext.Web.Lists.GetByTitle("MyDoc");                
                var item = spList.GetItemById(43);
                clientContext.Load(spList);
                clientContext.Load(item);
                clientContext.ExecuteQuery();

                #region customList
                Lists.Lists listService = new Lists.Lists();
                listService.Credentials = System.Net.CredentialCache.DefaultCredentials;

                listService.Url = siteUrl + "/_vti_bin/lists.asmx";
                XmlNode nodeAttachments = listService.GetVersionCollection(spList.Id.ToString(), item.Id.ToString(), "Title");

                foreach (System.Xml.XmlNode xNode in nodeAttachments)
                {
                    Console.WriteLine(xNode.Attributes["Title"].Value);
                }
