I've replaced a Bell & Howell worm just once, probably about ten years ago now. It was on a Magnaflex, which is a double band conversion of the TQ1 which somebody, I can't remember who, used to produce. This made it somewhat worse than doing a standard machine, but it took me several days of fiddling about, trying to work out how to dismantle the thing, just about everything seems to have to come out to get the worm out, and then to get everything set up correctly without the alignment tools. I wouldn't really recommend doing it, unless you had no alternative; it was something of a nightmare.

No, sorry. I don't know if the solid worms were ever fitted as original equipment, I've only ever seen them fitted as replacements. The problem type were fitted from new in the first generation of 'new' type Bell & Howell machines, i.e. the ones with the large diameter lens mount. I think these were introduced in about 1960 ish. Over here they would be the 642 and similar series, but I think the models, or at least the model numbers, were different over there. These were the ones with 750W or 1000W straight tungsten lamps and valve (vacuum tube) amplifiers. They were also fitted in the similar-looking TQ1 series with halogen lamps and the 666a (I think it was 566 or something similar over there) with GE Marc 300 lamps. I've only ever seen one TQII, and that had an old-style worm. I've never used, or seen the inside of, a TQIII.
