Electra Rat Rod frame number

[GooneyBird]

I've finally gotten my Electra cruiser, as there were some difficulties at the import yard. Anyway, I want to get it insured, as all my bikes are, and they require the frame number of the bike.

Now, I've looked up and down, but the frame number is nowhere to be found. It's not on the seat downtube, nor is it on the head tube. Where is it? Does it even have a frame number?

im sure you've already done this, but the first places i'd look is the underneath of the bottom bracket, and the rear dropouts. if its' custom, i know some guys will putty in the stamp for a smooth look,

Yup, found it. On the bottom of the bracket holding the cranks.
What a bloody annoying place, btw. All the bikes I've had, had it on the downtube.

BTW: It had 2 numbers on it. I just assumed the longest one (WMR****G) to be the one, right?

Thanks for the help guys.
