Bob: You may already have this but Walker, I.C., Nineteenth -Century Clay Tobacco Pipes in Canada, Ontario Archaeology, No. 16, 1971, gives some information about Fiolet and illustrates a few from Quebec City. According to Walker, the firm of Fiolet was in business from 1765-1921 in Saint-Omer, France. Pl. 5, Fig. 6 and Pl. 6 (center) show the marks "L. Fiolet/St. Omer/France" and "L. Fiolet/` St. Omer/Diposi". Pat Tucker [log in to unmask]
