Suppose $X$ is a topological space and $S(X)$ is the vector lattice of all continuous functions on open dense subsets of $X$. Although, $S(X)$ is not a normed lattice, we can have unbounded norm topology ($un$-topology) on it. On the other hand, the recent result, due to Wickstead, presents a representation approach for every Archimedean vector lattice $E$ in terms of $S(X)$-spaces. In this note, we show that this representation is order continuous and when $E$ is order complete, it coincides with the known Ogasawara-Maeda representation. Moreover, we obtain a similar representation for an order continuous Banach lattice in terms of $S(X)$-spaces that is a $un$-homeomorphism.
