This CD 143 C. N. R. is the style that the periods are shaped like prisms. A very handsome green and in very nice condition. Toward the top of the dome on the back side there is either a small chip or it could be simply a slight manufacturing flaw. Either way, it is minor and takes very little away from a fine looking Canadian insulator. How about $45 and that will include the shipping, U.S. or Canada
