Basically what I see on the pics is a Bf-109B or C Frankenplane grafted with a 4-blade prop.
Not that much in common with the HA-1112, as there are pretty obvious differences, like

• The engine cowling's shape is the one of the Jumo 210, it has nothing in common with the Merlin cowling of the HA.
  
• The exhausts' position (low) reflects to the Jumo 210 inverted V design, whereas the Merlin's exhausts are located considerably higher since the Merlin isn't inverted.
  
• No rounded wingtips.
  
• Wing cannons missing, instead there are MG-17s visible which aren't part of the HA.

etc. pp., it's nothing more and nothing less than an early 109 with a 4-blade prop on it.
