It gets frustrating when you are looking for answers and nobody speaks up but I understand that is the nature of the forums at times. I was waiting to see if anyone would add comments, good or bad, on the device in question. As Dave stated, when you don't know, you don't know what to add.
I got it from a well known collector whose name I'll leave out of it for privacy reasons. I mentioned the differences when I was initially offered the piece but decided to take a chance on it as these USC&GS badges are hard to come by as it is. I had sent PIC's of it to the NOAA Library and Skip Theberge who manages the library said it was the first example he's seen that he thought was authentic and wanted photos to add to the library for reference. When I mentioned the differences in the device compared to regulations, he didn't know what to say. I asked for any additional information but time and other things have kept him busy.
My gut says it's real and based on the overall design and hardware, think it's pre-WW2 but just how early I can"t say. The device does show traits that favorably compare to Navy and Coast Guard devices around WW1 and sometime thereafter.
I am trying not to drive the conversation in any direction but have photos and things to discuss, so with not much more "discussion", I will post the next photo and see what that generates.
The device came to me on this Pasquale Co. card of issue. The handwritten information could have been put there by anybody over the years, hence why I didn't show it earlier. Pasquale was in business since 1854 and they did manufacture all sorts of military insignia however, I cannot say with 100% certainty that the card originally came with the device; wish I could!
Appreciate any comments.
