I don't see any cracks. What I would call normal surface pitting. The ports may need to be cleaned up some. The first photos shows the one I am selling next to an unmolested one. ( the red one is not for sale) The end was broken off at some point and I cut it back to a clean surface.
Asking $20 plus shipping. Should fit large flat rate but will work with you on shipping to get the best deal with USPS. Pay-pal or check.
