Abstract: In this paper we list all the weight $2$

newforms $f(\tau )$ that are products and quotients of the Dedekind eta-function

$\begin{equation*}\eta (\tau ):=q^{1/24}\prod _{n=1}^{\infty }(1-q^{n}), \end{equation*}$

where $q:=e^{2\pi i \tau }.$ There are twelve such $f(\tau ),$ and we give a model for the strong Weil curve $E$

whose Hasse-Weil $L-$

function is the Mellin transform for each of them. Five of the $f(\tau )$ have complex multiplication, and we give elementary formulae for their Fourier coefficients which are sums of Hecke Grössencharacter values. These formulae follow easily from well known $q-$

series infinite product identities.
