That's the answer to the camera conundrum.
What Wiki says about them;
"The Halina 6-4 is a basic viewfinder camera made by Haking in Hong Kong. It has a focal-plane mask, allowing it to be set for taking either twelve 6×6cm or sixteen 4×4cm images on 120 film - and there are two viewfinders and two red windows to accommodate the two sizes.
The lens is labelled "Halina Achromat", with a maximum aperture of f/8, and Waterhouse stops for f/11 and f/16. The front-element focus is marked into three zones.
The shutter is single speed + B, with double-exposure prevention interlock with the winder. Flash can be connected using a PC plug.
The body has a lever in the base, detaching the back and baseplate for film loading. A small folding foot is built in to the bottom of the lens barrel to support the camera when standing on a flat surface"
And below some shots taken around Salford precinct with mine, it was my first camera and was given to me by my Nan, bless her.
