I believe the manufacturer is Fabrica Nazionale and it was made in Italy. I also found similar one for sale on ebay for $50. Mine is little more rusty but the other one was missing a part. I only paid 10 € for this. As most of my restoration projects, I bought through an online marketplace. Hopefully next summer, when there are more flea markets than during winter, I find items with more interesting stories behind them. This time I decided to do some experimentation with both my video editing and the processes I used. As usual, after disassembling, I removed the rust with vinegar. I didn’t put the handle in the vinegar as it had wood and vinegar would have turned the wood dark and water wouldn’t have been very good for it anyways. There were also some red and black paint on the parts but the vinegar softened the paint enough to get it off rather easily. Despite this it took me several hours to clean up the parts. There was also some black stuff inside the grinder. I think it is some sort of oil from the coffee beans. After experimentation I found that acetone dissolved it so I had to go through the insides by scrubbing them with acetone. Now what the grinder was clean I thought it will rust from the inside if the metal is not protected. Paint is most certainly not good idea as it is a health hazard, so I thought of gun blue. After some research I decided that I would have to consume A LOT of the coating during short period of time to get a poisoning, even if the coating was very thick. Most likely issue would be copper poisoning, in case you are curious. Some of the coating will be eroded to the coffee but we are talking about extremely small amounts that are not a health hazard. Body will naturally get rid of all the substances in the bluing solution. However, it is important to clean the parts with a lot of water. In the video you only see me neutralizing the solution with wet rag to stop the reaction. After this I also washed the whole grinder, as I mention int the video. The solution itself is much more toxic that the coating because the coating is so thin. This is just my personal opinion and you shouldn’t base your own decisions only on my opinions. I am not a toxicologist but I do have enough expertise and understanding to evaluate the risk for my personal use. Anyways, On the handle I decided to go with red, it had originally been gray but 1. I wanted to try out 2K spray paint and I couldn’t find any in gray locally. 2. Red looks great with the blued steel but it is still very traditional color. I also removed the old wax and dirt from the wooden part of the handle. I tried what colored wax would have looked like but I was not confident it would look good so I decide to try the colorless wax and it looked great. I had not expected it to change the color so much. I tried colorless first as I could have applied the colored on top of it if I wasn’t happy with the colorless wax. I put a coat of oil on the metal surfaces to protect them further from rust. This grinder will now last forever. I can also wash it as it has the coating on the inside too. Without coating it wouldn’t be possible as the inside would rust immediately. After disassembly I tried it out and it worked very well. I will throw away the first few batches just as a caution if there are any unwanted residues that would adhere to the ground coffee.
