The Pilgrims played out a 1-1 draw at Plainmoor on Saturday in a testimonial for Gulls midfielder Tony Bedeau.
"He's a class act," Williamson said of West after the game.
"You can see that he's played at a level. He does the simple things well and when questions are asked, he normally stands up to be counted.
"He wants to pass on his knowledge, as well. He'll talk players through games and, if some players can learn from him, it bodes well for the future."
