Looking for a trailer wheel

Hello,

I need to get a wheel on which to mount a spare tire for my trailer. The two wheels on the trailer now are manufactured by Lemmerz. Over the manufacturer's name is the marking "1345-2" and elsewhere the size designation "4 1/2 Jx13H2" and still elsewhere the designator "ET27". It has a four lug pattern; I haven't measured the center-to-center distance on the lug holes, nor the diameter of the center opening (I hope that all that information is somehow contained in the various markings and designations). I can make those measurements, of course, if necessary.

The wheels I have are good, but I need a third so I have a good spare. My favorite tire store told me to check out the junkyards to try to find a replacement; I thought I'd check with this group.

Anybody have an extra one of these they'd like to part with at a bargain basement price?
