6V81 1928 Belmont-Severn Tunnel Junction question 1983

[Rover]

Would anyone be in possession of a supplement to either the Eastern Region YE/YJ or London Midland CX freight timetables for January to May 1983 to able to check the timings of the following through Chesterfield?

The May 82 to May 83 timetable has a 6V81 1928 Belmont-Severn Tunnel Jn ABS Speedlink service due to pass Chesterfield at 2028 which it usually did up until January 1983. From January 1983 it appeared to run around 75 mins earlier at around 1915 regularly which doesn't fit with a 1928 departure from Belmont.

However, from the May 83 timetable there was a 6V06 1648 Healey Mills-Severn Tunnel Jn due Chesterfield at 1909, did this service start from January 1983?

I would be most grateful if anyone could enlighten my darkness.

The Chesterfield Observer - introduction​

Greetings!
I'm a trainspotter and I mis-spent my youth trainspotting to the point of obsession at Chesterfield railway station in the 1980s! - but I don't regret a second of it! (Well actually there were occasions when I thought 'what the hell am I doing here'!)

What is The Chesterfield Observer?
Detailed observations of passenger and freight workings passing through Chesterfield from 1981 to 1992.

Who is it for?
Anyone interested in day to day workings of trains in the 1980s. It could be useful for historians, modellers and anyone requiring detailed information about railway operations from a bygone age - perhaps?

How do I use the site?
Information is all in chronological order.
On the left is a "Date Selector" and a simple "Search Box".

A brief scrutiny of January 1983 suggests that 6V81 may have changed then to 6V06 1648 from Healey Mills.
