Sorry, but I also had my computer die and was not able to replace what was lost from this site's crash. The grates are made of cherry and are replacing the ones that were sent with the kit. The deck planking and lots of other things that were not correct in the model will be replaced with items that are in proper scale when I get back to this model. The newer version of this kit did away with some of the parts that were included in the previous model by this company but can be ordered from their catalogue. This I did and thus started working on the Sovereign while I was waiting. Mantua takes a while to get their parts. I knew what parts to get since I had started this model and was close to starting the rigging when the model was burned in a house fire.
