That looks very much like the HMV 97, as illustrated on this page --

To the novice collector, many of the HMV portable models seem very similar in appearance, but there are some differences, which are especially noticeable if you compare them side by side.
For instance, the HMV 101 is equipped with a long, very thin, gradually tapering tone arm, and, of course the HMV #4 sound box, which has a large mica diaphragm. It also has a record storage compartment built into the (inside) lid.
In contrast, the later production HMV 102 has a fatter tone arm fitted with the #16, or the #5a or #5b sound box, depending on the year of production. These used aluminum diaphragms, instead of mica. In addition, there is no place to store the records in the HMV 102's lid. Instead, these were equipped with a round record storage tray that fitted onto the turntable.
There are many other differences between the two models. If you're curious, try to hunt down a copy of "The Perfect Portable" by Dave Cooper. (FYI --
