I had been watching this pipe on ebay for a while, and finally decided I had to try to repair it, so I made an offer and the pipe arrived yesterday. The pipe and stem fit the case perfectly and there didn't appear to be any structural damage, so I figured there 'had to be a way'.
Once I got started I discovered a few problems: the right ear had broken off long ago and been glued back on crooked. The shank had a break and fill that were disguised by the color of the shank. The tenon was wrapped in thread and fit loosely into the shank.
I began with the meer insert, thinking that whatever technique I came up with that worked on the insert, would be good for the horse head as well.
The main tool for the project was a 1920's pocket-knife with a dull 1.5" blade. With meer I've found that sharp knifes can catch on rough spots and cut into the stone, whereas dull knives can still scrape off undesired material effectively, but rarely damage the carving. The hard black crust came off in chunks, then I scraped off the smaller bits and finally scrubbed with a Magic Eraser to get off the last bits. I rubbed in jojoba oil, buffed, rubbed in Clapham's beeswax polish and buffed. I decided that, for the stummel, I would scrape, scrub with toothbrush and water, rub in Jojoba oil, let it dry, then decide where to go from there.
Here's the stummel part way through - see how the black stuff was literally peeling away. After getting all the black (and dirt) scraped off, I worked on it with a magnifier, dental pick and the knife, until all foreign matter was gone.
