campagnolo strada drive side crank triple chainring 180mm

Very unusual campagnolo triple speed crankarm that still uses 144 BCD chainrings. Also is an extra long crankarm being 180 mm long. Includes a stronglight chainring and specialized smaller chainring. Four out of 5 chainbolts are campagnolo branded. Has hairline crack in the area between the crank and spider (check pic for more)
Because of the unusual size and wear, im open to any decent offers. Want this unique crankarm for anyone who is intersted in this particular component.
