Thorlabs KS05(/M) Ø 0.5" Ø 1/2" Precision and similar items

THORLABS O12.7 mm Precision Kinematic Mirror Mount, 3 Adjusters, M4 Taps + 0.5" laser filter (broadband?) Description: a mini precision kinematic mirror mount with a laser filter mounted from a R D lab. closed down. You would need a typical 2mm allen tool (2.0 hexagonal) to move the kinematic screws. It has an unknown high end laser 0.5" filter, seems to me a bandpass filter in the IR range (very light blue coating/reflection). It is the "middle" placed stage in the first picture. It allows for left or right hand orientation (you can change it easily). It is a metric device with METRIC screws and pitches. Measures: https://www.thorlabs.com/drawings/f57cd140fe311b1f-084FA729-9627-553B-DD6EA3EB8E794D85/KS05_M-AutoCADPDF.pdf Other measures: Base dimensions: 30x33mm. Total height: 46mm. Condition: used but in perfect smooth working order. Like new condition. Lens is glued (seems heat-melting glue) to the mount. There is missing the normal locking screw ("NYLON-TIPPED LOCKING SCREW 2.0mm [5/64in] HEX FOR SECURING OF OPTICS"), which is a normal M4 (metric) allen head grub. I send a metal M4x3 replacement, but it would be a great idea to get some plastic M4x3 grubs (very cheap all over or similar sites) to protect pricey optics. Only ONE mount (the one on the middle first picture).
