Congratulations with your recent purchases ! Great items !
I think I must have met the 'Belgian' seller you met at Beltring . This was at a small militaria show in Belgium, July 5 .
Unfortunately he brought along some Syringes + Armbands . He told me he had made a bid at an auction run by a local civilian hospital around in Brussels (that will be renovated, they were getting rid of old stocks), and won it . He only told me about the syringes, and said there were some odd items too, including the armbands . He at first desperately tried selling me some armbands, but I told him they weren't the regular US type, then he came up with a story (sounds familiar to you ?) that stocks were taken over by the US Army and appropriately stamped ... for use by the US Med Dept !? But, what about the other numbers ? Did you measure the stamps, are they inches or millimeters ? Just keep us posted ... Thks
