Ku Luger on Gunbroker

I admit that I have not read the article and I will try and do so this week. In the mean time I would like to find out what in the heck the Coastal Police were as I have never been able to find even a passing reference to any such organization. I am familar with the Water Customs Police and with Naval (KM) coastal patrol units but not the coastal police. If they existed they must have been fairly large to warrent (pardon the pun) a direct special assembly out of factory for an estimated 5000 Lugers.
