M_Boats: Re: M-15 Trailer Info.

The trailer for my M 15 has the following number stamped on it. TTO-56845 I assume this is the VIN. I am going to try to get a title and registration on it. I need the Mfg. name, year and Vin. The boat sail is No. 242 (I think). The trailer is painted and has no tongue extension. Any info on Mfg and year? Ken Abrahams
