This is a 3D printed item, using a fine ABS like resin and comprises of a kit of parts for a complete vacuum brake cylinder, including the piston and support brackets (enough for one GWR Class 51xx Prairie locomotive).
The 1st photo shows the component parts as they will be supplied, before any clean up. The 2nd and 3rd show the cylinder assembled.
Bear in mind the size of these items when looking at the detail in the photos. The cylinder is 14mm diameter and 4mm deep. The width across the support brackets is 24mm, but can be extended to 26mm if required.
Please ask if you have any questions or if you need a variation on this theme.
