The invention relates to the field of criminalistics and can be used to identify and register remote factory marking on metal parts in the process of chemical recovery is deliah, hours, orders and other items with individual factory marks.It is known that the use of methods of labeling in the process of factory manufacturing products allows them to individualize and deleting (cutting, hammering) marks in order to difficulties of identification it is possible to restore one of the following methods: chemical, electrochemical, magnetic suspension, x-ray. In expert practice, the most commonly used chemical method, which is the most easy to use and reliable results, which is based on the difference in chemical activity of the deformed and undeformed areas of the metal surface: chemically active and quickly dissolved in the reagent areas in which structural changes occurred. As a result of uneven dissolution is the manifestation of the shapes of the contours of the factory marks that were removed 
However, from the viewpoint of ensuring the registration of the restored factory marks after it changes, the device selected for the prototype, has several disadvantages. With this device the resulting fragments factory marks marks because the identified image (movie sign) just disappears. The photographic condition (have to photograph through the thickness of the solution, which has undesirable effects on the optics of the camera) does not allow to obtain high contrast images. Due to the fact that the fixation marks restored marking simultaneously, part of the useful information about the original marking is lost.The technical result is to increase the accuracy by providing the possibility of creating a total image of the restored fragments rooms for all the time of development.The result is achieved that the device for recording the restored factory marking, which is a fixing apparatus, characterized in that the fixing apparatus is a television camera with a transitional unit of input television signals to a computer, summarizing image restored fragments of non playing characters on the monitor and a printing device.The drawing shows a scheme of registration of the restored factory marking.The device comprises a recording signal from the cell 1, which is installed on the surface of the marking platform 2 products, the television camera 3, the Fort worth 9.The device operates as follows.After applying power, regulate the distribution of illuminators 9 thus, to obtain a contrasting picture of the surface relief marking pad 2 products on the monitor 6. Then in cell 1 with walls of clay fill etching solution corresponding to the composition of the alloy product and allowing the process of etching the surface of the marking platform to identify fragments recovered factory marks at different points in time. With the television camera 3 image fragments recovered factory marking using a block of input television signals 5 are entered in the computer 4, in which digital frame images are formed. The speed of the input frames from the TV camera 3 is governed by the commands from the keyboard 7. Total image fragments rooms during etching marking pad 2 products generated by the program on the computer 4. Restored factory marking is displayed on the monitor 6. If the contrast is obtained on the monitor 6 image restored factory marking is deficient, it may be raised about the usual printing device (printer) 8.The device for recording the restored factory marking provides the following benefits:
allows you to register restored factory marks marks that are impossible to capture photographically because of the low contrast of the obtained images;
ensures completeness of the information on the factory marking (faces of characters), preserved in the surface layers of the product;
