You would normally expect when a company brings out a model, it remains unchanged until replaced by another model. There are so many variations in the Bell & Howell TQ1. One has Bass and Treble controls, another only has a tone control, one here has two other controls I haven't seen before, then we have one with a non metal loudspeaker grill, and another that has speakers front and rear The same goes for the later TQ models. The same can be said of the Filmo cameras; many are identical in every way, just a different model number.

It beats the crap out of me too Robert, I am left at the starting post at the models put out, probably a marketing ploy to rebadge the previous models by making little changes to suit.
