This is a better picture of the 141 that I posted yesterday. Am thinking. . .that this variant. . in light aqua. . .is pretty scarce. Have seen numerous of the dark aqua and dark green type. . .as these were widely used on the transcontinental telephone line that ran through the Sierra Mountains East of my dog house here in sacratomatoe..

Any takers on how common/uncommon these are? Are they underrated in the price guide? Any clues on who made these?
