I got from Mr. Dies van Nieuwenhuizen that he believes that the tug behind the BARBER TONSBERG on the Panama stamp is the AMISTAD but he can’t remember more were he got the source from many years ago. By looking at the stamp even when I enlarge the image it is a tug but I can’t make much more out from it. Who can confirm or deny if the name is correct?
By looking in https://www.miramarship.nz I found that three tugs were built by Bollinger Machine shop & Shipyard in Lockport, Louisiana for the Panama Canal Authorities. It are sisterships.
