This is just one delft blue McLAUGHLIN No 42's of about 15 that were recovered on a recent hunt. The embossing is super bold and have not seen another with this bold of emboss. The letters really stick out a long ways front and back of the insulator. I have this one and one other up for sale and asking $45.00 for this one. Email me if interested and will give further information about purchasing.
