I have 13 pair of Kadee 1906 couplers, lightly used and with the coupler hose cut off. I also have one with hose that was only used on my coupler height gauge and one pair new in package. I’m offering these at $1 each for the used ones and $4 for the one new pair in package, For a total of $31 for the lot plus $10 shipping anywhere in CONUS. See photo below. You also get all new mounting hardware and a bonus 4-40 screw and nut that are keeping each of the coupler parts together.
PayPal preferred but personal checks and money orders will work as well.
