Anyone know where I might source a B31 plunger oil tank (I know about eBay etc)? I'm doing some repairs on mine but would like to replace it with a less corroded one.

Should be able to source one on Ebay a bit closer than 6000 miles though!
I have an excellent plunger oil tank on my bike, but it should be the type with the larger wing-nut cap and that's what I'm after.
If anyone has one for sale.....
Thanks, bit of a lottery buying without decent pics of the inside (which is hard to do). Just contemplating making one. Not too fussed about originality as long as it's healthy. Anyone else made one?
For context I cleaned mine out with paraffin and a few nuts shaken around inside. Revealed a load of pinholes including in the breather tube. I cut the tower off the top to replace the breather tube as it was full of crud and rust. With the rust brushed off the inside and outside of the tower it's as thin as lace and has plenty of pinholes. I tigged it back on where I could but had to use filler for now to fill the pinholes and fill along the tack welds. Not good but should do until I come up with a better solution. Have considered making a new tower out of tube/hollow steel sphere but it seems like flogging a dead horse.
If you can polish the metal to a shine, then you should be able to solder the pinholes. Just punch the pinhole inwards a bit with a small ball pein hammer, then solder flush to the surface. Any excess solder can be filed away. Soldering was the preferred method for car body repairs, before fillers were available, some would even do large areas with the lead.

To add to my own post, anyone know if a rigid bike's oil tank (which came with the larger filler hole) would fit? The mountings appear to be the same.

Yes, the oil tank from a rigid bike fits.
Thanks Derek.
