I am unsure if this is a 6V or a 12V. It is marked RBM & 3600-2. I picked it up on speculation, being told it was a '55 Packard. And I expect that it is a relay...
Maybe you guys know?

Looks like an OD relay to me.

If someone with a known 6v relay could check and see if the same 3600-2 is stamped on theirs it might indicate whether that is a valid part number that could be used for identification. Perhaps the -2 is denoting a 12v model and an original 6v relay would be different with maybe a -1 or even or missing the extra number entirely.

Probably not much help since there is no way of telling if the relay was from a Packard or if it is the original fuse but Packard wiring diagrams say a 6v version would have a 30 amp fuse and the 12v has a 15 amp.

A Google search for RBM 3600-2 comes up with 2 links to restorecarsclassifieds.com that both show the 3600-2 relay for Packards with 6 volt systems

It seems to cross over to Packard part number 403940 and if you are looking to sell it, please PM me with the price.

The fuse is a 30 Amp :)
