$950 NOS Flight Control Tower, the stamping on the top center is 220 05 021 (see pics) and appears to imply 2005 model year and originally intended for a 220. Although stamped 220, i used the sister unit to this one on my 210 with no problems, i think the 230 are longer but not 100%. I purchased this tower with several other surplus new units in package deal from a cc dealer in 2008 as I needed a replacement for the 210, and it has since been in storage. Storage is getting full, so up it goes. Although this unit has never been installed on a boat, it has sat in storage and has gotten a few scratches over the years, nothing that couldn't be remedied but I want to be clear it is not 100% pristine off the factory floor but it is close and is priced accordingly.
