I've been working on these today and I'm feeling guilty because it's been a long time since I last used them, one is a very late RM1 manual load which I've had for many years and is the quietest Elf I've ever heard, it was my main machine for some time, the second is an NT1 with auto load which I bought as a second machine for features along with the RM. I bought a couple of Elmo CLs and put the Elfs in the cupboard, the Elmo's are so easy to use and run very quietly but the sound is better with more control on the Elfs.
Both machines you could tell have been sat unused for a while as both sets of arms were stiffer than they should be to raise, all the plastic rollers turned freely but I cleaned and lubed them, both lens rubbers are good, the back came off to reveal still soft grease so a wipe over and re grease was all that's needed, they both are running well so I've decided the next few films will be run on them, Mark.
