Once the clamp assembly is removed there is nothing holding the base plate other than friction and, maybe, the tightness of the grub screws. The fit is fairly tight, just get a copper hammer and it will come off. The marks are the nominal position to centre the tailstock.
The grub screw are there to move the tailstock, thereby offsetting the centre, to allow the turning of shallow tapers

Thanks again Graham I got there in the end, the tail stock has had a hard life by the looks of it, its very simple no bearings, washers etc, she is a little sticky at about 3mm and the handle to lock the slide is stiff.
Sorry the crappy pic hopefully you can see it has some damage.

Some people are a bit ham-fisted. Probably school kids. The eccentric is very easy to bend over time, I had the same problem with mine.
Did you manage to removed the barrel? Mine had the end of the feed screw belled over from years of abuse, took a hell of while to get it apart.
Re the lack of bearings etc., I decided to modify mine and put a ball bearing in a new end cap. It's well worth doing once you've got yourself sorted.
Measurements, I just copied what was there with a bit of scrap mild steel and bought a bearing to suit the spindle.

That looks like a good idea. Every think came apart ok the only bits i did not strip where the locking handle mechanism and the threads from inside the barrel.

To remove the chuck rotate it with your right hand whilst pressing the chrome button on the front. it'll drop into a slot. That button is the spindle lock. DON'T use the chuck key to remove the chuck. If it's tight it'll damage the screw. Use an adjustable, or other spanner that fits the flat on one of the jaws and apply force with that. It shouldn't be too difficult.
Headstock. I'll post later. Just off to a welding course

get a piece of flat bar, 25mm wide, locate the headstock lock (To remove the chuck rotate it with your right hand whilst pressing the chrome button on the front. it'll drop into a slot) and clamp the flat bar in the chuck, use that as a lever to start the chuck coming off.

Regarding the headstock - unless you really feel like doing it, or there are obvious signs of roughness as you turn the spindle, then it's probably unnecessary. The spindle can be very tight in the bearings needing drifting out. I used a press when I dismantled mine. The wires you mentioned are for an interlock on the back gear lever, so that it can't be moved under power.
The bearings can easily be checked by removing the alloy caps around the spindle, 3 cap screws. Obviously, any hard grease needs to be removed and the bearings repacked. Make sure the pulley groove and the body of it are thoroughly degreased to prevent later slippage.
The spindle should be lightly pre-loaded and be a little stiff to turn. This is adjustable using the two lock rings at the left hand end. The setup requires a spring balance, a chuck and some string. I can't find the specific details at the moment but I'll keep looking.

Sounds like a pita I will leave it as is and clean what i can without taking too much apart, the 3 jaw chuck needs a strip down so that will give me something to do.

Had a little look at the headstock everything looks very dry. Oil of grease on these bits, i've also noticed a nipple next to the pulley grove.
Is it normal for a bit of play between the pulley part and the spindle? (it knocks)
I suppose the grease could do with a refresh.
Sorry for the 1000 questions
Anything to be aware of when stripping these down, on reassembly do they need anything special doing?
