This is my new project and I heard that this petrol tank is a tank converted by Fritz Egli in the very early years. Is this true?

Yes, let's follow it. We haven't seen, (well I haven't) a project thread for a while.
What are the telescopic forks off, are you going to keep them? The wheel looks like it has a good sized brake?
If the fork & tank mods were made by Fritz, then it is an historic bike and I would suggest it should be preserved as such rather than "restored" to original Vincent factory specification?

This bike was put together from parts and the fork is from a Horex and the frontwheel is a Münch Mammut one.Unluckily the hub is cracked and is made from magnesium which can not be weldet I think.The UFM is the early type with no slot for the rear damper.

If it were me.. I would swap the UFM for a Series C rather than cut the early one. That should be cost positive for you i.e. you will end up with a UFM plus cash. Sell one of the gearboxes. Buy a Suzuki GT750 front brake. Good hunting.

My Triton project was with a Manx rolling chassis but front conical hub had so much electrolysis action from the cast iron insert that it exploded, so the rear I swapped for a normal Noton wheel. Magnesium brake plates I've just removed from my Lightningised Rapide done in 1953 by Clifford Brown for my deceased mate Robert Fabian who had his first Vincent stolen, has all been stripped vapour blasted and haven't replaced anything other than rings, excentric shims, RFM pivot shims, no feeling of Brinnelling, but not progressed for 3 years too many other jobs in keeping the "B" going and electric start fitted with a quick strip for main bearing renewal and so it goes on, with a massive deviation in purchasing a 1919 "V" twin JAP engined Sunbeam with original chair. Does anyone know what the fully advanced position of the mag should be ?? Side valve engine.
Anyway, keep the project going, it's nice to read someone is productive!

Marcus, Go for around 38 degrees advance with the JAP to begin with, you should have manual ADV/RET anyway so you can see how it runs, Which engine is it by the way.
Erik, Magnesium is easily welded these days.

Tonight I will dismount the tank and will do Fotos from the large cutout on the left and the third thread for a tap in the front edge .

The top decal is pretty rare. Someone would have had to gotten it from Fritz. I am a little surprised that the cut-aways for the forks are so rough compared to the rest of the tank.

It does not look like Margret's Comet in the photo. Margret and Fritz visited the UK, as I remember, and sprinted their bikes at an event. They later married.

An interesting project!

The tank is very rough welded and the front fixation eyes are not very good fitting. I will post photos from the underside so you can see that it is a converted original tank. What I `m thinking about is to bring it in the old shape because girdraulics will be fitted on this bike .Erik
