Thinking of a new project of a 2-6-2T saddle tanker based on a aristo 2-4-2 rogers, I have 1 section of the saddle tank left from a project of “Rosy” + the rear chassis of a 2085 mallet and a new 2-4-2 rogers, starting to gather parts and am now looking for a source for some sand domes that would look good with the existing steam dome so any suggestions on where to look would be appreciated, the need to be about 3/4" x 3//4", thanks Bill
