Original Impressionist style Fishing Boat signed oil painting

I have an original oil painting of a fishing boat signed by the name which appears to be Tucker. It is painted on a professional quality watercolour drawing board with hardboard covering the back. There are some handwritten numbers/sums on the inside of the rear cover. I have not been able to pinpoint a specific artist with this name, I may be misreading the signature. I also have another painting in my listings by the same artist in a similar style which is signed as G Tucker '69. They were bought by my grandparents at least 25 years ago in Cornwall so they may be from a local artist. I have listed it as "Satisfactory" due to the age and condition of the frame even though the painting is in great condition. Similar paintings have sold for £120-£180 on auction sites but please feel free to make an offer
