    I've been rummaging around to find various avenues to find a marr that took
    place Nov 1838 St James, Paddington, Middlesex, but so far it seems the Nov
    and Dec PR is missing. has any one uncovered it where it may be hiding

The Register of Marriages Oct 1838-Dec 1839 is not missing. It's exactly where it should be, at the London Archives (P87/JS/021), but the images aren't available on Ancestry.

A bit more ...

line 1 - cora(m) d(omi)no Officiali

line 3 - relicte et executricis … Onusq(ue) execuc(i)o(n)is ('and the burden of execution ...')

line 4 - Com(m)issa est … prius iurat(e)

Should probably be … ad faculta(te)s mag(ister) = 'Master of Faculties', an official of the Archbishop of Canterbury who could authorise dispensations for things that were normally prohibited.

In the name of God Amen, in the year of the Lord one thousand five hundred and nine, and on the first day of the month of July. I, Ellen Alford, sound in mind and of healthy memory, make my will in this manner. First I bequeath my soul to Almighty God, the Blessed Mary his mother, and to all the saints, and my body to be buried in the parish church of Meer. Item, I bequeath to the fabric of the church of Sarum, 12 pence. Item, I bequeath to the high altar of Meer, 12 pence. Item, I bequeath to the fabric of the same church, 20 shillings. Item, I bequeath to the chapel of the Holy Cross, 6 shillings 8 pence. Item, I bequeath to every light existing in the church of Meer, 4 pence. Item, I bequeath to every one of the fathers of the church, 4 pence. Item, I bequeath to Master Christopher Chater, six shillings eight pence. Item, I bequeath to the High Cross, 20 pence. Item, I bequeath to every [p'bro] in the church of Meer, 3 shillings 4 pence. As to the rest of my goods not bequeathed above, I give and bequeath them to Thomas Alforde and Edith Carpenter, so that they should arrange and dispose them for the health of my soul, just as will seem best for them to do. With these witnesses - John Wattes, John Smyth, with others. Item, I will that the aforesaid Thomas and Edith be my executors.

(One word I can't get, but it may come to me later.)

The problem is the Culcheth registers have many missing pages.
You can view the book of the registers on MyHeritage. (I can't see if the registers are on familysearch, as the 'search' and 'search catalogue' facilities are not working - they have done a big 'update' - HA!)

It looks like whoever was the incumbrent there in the mid 1600s did not do a great job at keeping up the registers. Perhaps there was no incumbrent for some of the time, (it has been known).
Between about 1654 and 1681 there are no marriage entries at all, and some of those years there are no baptisms or burials; some years there are just one or two - usually for the family which looks as though they were the Lord of the Manor, (Holcroft) - perhaps he filled in the register himself.

It looks as though these are the years in which the other children will have been born.

But those registers on MH and FamilySearch, with so many missing years, are surely the bishop's transcripts.

The extent of the early surviving parish registers for Culcheth can be seen in the online catalogue of Cheshire Archives ...
