Your rifle is basically a Squires Bingham Model 20 with a barrel shroud added. No better, no worse than the standard SB as far as quality goes. I don't think there ever was a drum magazine made for them. If you can make up something that will work, great.
Have a look at the threads regarding Marstar bringing in the PPS-50s made in Italy.
The Squires Bingham was introduced to compete with the Pietta. Very different rifle.
There are two similar SB rifles, the M50-3, and the PPS-50. But don't confuse the second one with the Italian rifle.
FRT #s are 35503 for the M50-3, and 56077 for the second.
