*   Siemens list prices refered to are those in the only printed price list that I have from Siemens, and are basic list prices before any discounts. That price list is out of date, so current prices may be more or less. Prices thus stated are just to give a rough indication of what you might expect to pay if buying the item new from a Siemens distributor. Ebay typical prices where known are an indication of what I have seen similar items selling for on ebay recently. Any prices marked ?? means I have no comparison data.
