Looks like there is nothing critical missing. Mitre guide would be nice, but not essential. Ask if this is hiding somewhere though as replacement is tricky due to the non-standard slot it slides in.
As it's going to be a cash on collection deal, make sure it turns on and have a look inside before parting with cash. If the wheels seem to be running freely without wobble then there isn't much else that could be wrong with it.

I think it will go for £175-200. you may get lucky for a bit less. There is a lot of bidding for something with a couple of days to go.
That colour scheme is one of the older ones I think, the later ones were darker. That is not to say it is better or worse than any of the others, just noting. I think that it is Swiss made rather than French.
