vintage Siemens Movie Camera 16mm made in Germany

Vintage Siemens Movie camera ,made in Germany, think it is a 16mm format,looks in very good condition other than the leather strap being cracked & some crazing on the black paint to the top viewer,seems to run when move button to 'TB',lenses look good- no observed scratches or mold-although they may need a dusting. We don't know much about cameras so this is being sold 'as is'.Thanks.
