I do not know what information you have; or, were you are seeing the information; nor, that "14505 PT950" reference ...
That said ...
As you referenced Scotland ...
I just took a quick look in the website:
maintained by the Government of Scotland
FREE to "Register" as a User and look at the "Indexes"
ONLY cost is if you want to look at a "Image" of an "Index"
where you have to purchase "Credits".
I found this ...
Here is a "Close-Up" ...
I hope this helps.
I am also not sure what the number is. Please give me a little more information. What is your great grandfathers name, date of birth and location. If he is in FamilySearch the PID would also be helpful. I will see what I can find.
Thankyou for using FamilySearch.
I believe it is a film number and will show the birth record of my gr-grandfather, birth name Thomas Tudehope (could be Tudhope), born 28 Dec 1852 Wishaw Lanarkshire Scotland to Rachel Young, no father listed. Thomas Tudehope was adopted in 1858 by James Weir and used both last names various times in his life. My family tree follows the Weir line. However, I am interested in the Tudehope line since we have much information regarding his history. Thank you
Amazing information. I will definitely check this out. Did not know that website existed. So much to learn. Thank you.
