Here is an odd one ... Paul Greaves and I recovered two of these last year near Redding, Ca . We also found pieces of them on a different line out in the Weaverville, Ca area and have seen pieces of at least half a dozen more ... What is odd about this piece besides the colour ? The top is marked with the # 7-1 Fred Locke marking and is MLOD (1903-04) and the lower bell skirts are marked VICTOR and were produced in the 1906-08 time frame We found both marked and unmarked examples of these ... the question is why? Some speculation is in order . The Northern California Power Co was a real shoestring operation that floundered near bankruptcy for a number of years and clearly bought random insulators from various sources perhaps at a discount for their lines . Over the years we have seen early multiparts with later replacement tops where the top skirt was damaged in some way and a new top cemented on as a cost cutting measure ... but to find an early top with later skirts is just odd ... especially a quantity of them . Normally manufacturers did not ship extra tops so having a surplus of them would be odd . One possibility is they cut a deal with the Victor factory for some insulators comprised of surplus old stock insulator shells still at the factory at a discount . the other possibility is PG&E somehow ended up with some surplus M-4384 tops and sold them to their neighbour up north who ordered lower skirts from victor. This same line had the weird brown M-4321's and M-4325's with Gray inner skirts so we may never know ... none the less, these weird hybrids make for some dam cool looking insulators!
