Hi Andrew,
That one was just a shell, and it had been oiled or lacqured, the high gloss is a sign that the finish has been doctored, While it is not a bad thing to have a dress helmet that has a high gloss, a Stahlhelm would never have been finished with such a shiny surface. The selling price was pretty high when you calculate in the shipping cost. Remember to ask the cost of shipping before bidding on a large item, or you my get an unpleasent surprise. A few more things to watch for on ebay seller's is their feed back, if thye have negative feed back, read it to see if it was justifyed before bidding, watch out for sellers who hide their feed back, as there must be something wrong. Sellers who hide the bidder's ID are suspect, as many who sell bad items do that so the bidder's can not be warned by other ebay members. If you bid on some of the European ebays, be careful of using a decemal instead of a comma if you do not use round number bids, for example a bid of 10.10 euros on a German ebay auction will be 1010 euros as the comma is used in Germany
