Manual/Schematic for older 550

A friend was given an older 550 setup by a widow. I may trade/buy it from him and we are trying to see what parts it might be missing or need replaced. The schematic from the 550 manual download doesn't match up. Are there older versions of it available? Were there different or distinct versions of the 550? If so is there a way to ID the one we have? It is called the 550B, was there an 'A' or base model?

The press is in a lot of parts. The powder measure doesn't seem the same as the one in the manual either. Also, have all 550s came with an auto primer? He doesn't think this one has one. I've got it all in front of me and am trying to match things up and take an inventory; It is quite the project! I have reloading experience, but not with any Dillions. I could use an older manual for Dillon dies too.

Sorry, but no older exploded drawings are available. There was an earlier version, called the "RL550". It lacked the low primer alarm, the mechanical failsafe return rod and bracket for the powder measure. The older powder measure has a different design to the bellcrank (the stamped steel arm that pushes the powder bar over), and uses a spring or two to retract the powder bar.
All RL 550s included the automatic primer feed.
If necessary, please take some photos of what is there and email them to us, for better identification of what is missing.

It has the old style failsafe arm. Is this something I need to upgrade for safety reasons?

I need to clean and lube it also, the original owner used cast bullets and there is bits of old hard lube around. I think it needs to be taken apart. I've looked at the video some.

Is this able to use current parts if I find something missing? All of the primer parts are there, expect the alarm, which you said wasn't included in the older model. I think thats what threw us off.

On the RL550, because the shellplate is manually indexed, there is no safety advantage to updating to the two-piece bellcrank. All current parts fit the older versions of the machine, no worries there.

In another post about lubing a old 550 you state:

"Then you will need to partially disassemble the machine to lubricate it, as shown in the video for major cleaning and lubing the Rl550B. Please email us and include your address. We will mail you a upper link punch and a platform alignment tool."

Could I get that punch and alignment tool also?

Please phone or email your request to us. If you email us please include your address.
