Dylan 550 series presses

[CRAPPIEfish]

What is the visual difference between the 550, 550 B, and the 550 C. I haven’t fooled around with this stuff for 10-15 ,  more or less years and have no idea what I have. I have no idea where the receipts are for any of this stuff. Like I said, I haven’t used it in quite a while.

The 550 B added the low primer alarm and the powder measure failsafe linkage to the RL550. The 550 C changes are more subtle. The "C" added a screw-in upper link arm pivot pins, and a grease zerk fitting to the lower link arm pivot pin.

, I appreciate your answers, but do you have any photos of what I am supposed to be looking for?   I don’t have any of my old manuals or at least I can’t find them for a reference.. I have tried to look through the Dillan stuff, but I cannot find a picture of what I’m supposed to be looking for.

TIA, CRAPPIEFISH

if Its been 10 years you can eliminate the C. If you have the audible alarm on the primer tube its a B. If not Its a 550
