RALEIGH FRAME NUMBER DATING. MY NOTES: 1.The Raleigh Heron Head transfer was introduced in 1908. In the same year, mudguards received a forward extension. Raleigh’s ‘R’ lamp bracket was superseded in September 1927 by the heron lamp bracket (see below). Date Raleigh by serial number? A couple of days ago I posted an inquiry about a Raleigh steel frame I have that has been painted by amateurs, and has no decals or anything on it. I suspect it is a premium quality frame due to several things.

Before I start, let me unequivocally state that I'm under no delusions that I have a gem on my hands. This is simply a curiosity that I'd like to answer.
I use an an older steel Raleigh R-100 as a dedicated trainer bike. Since it was a craigslist find, I don't know the history and the bike has a mix of parts, none of which seem original;
- FD is Shimano 105, no externally visible series #
- RD is Shimano Sora, no externally visible series #
- Crankset is Shimano FC-1051 (square taper), which I understand to be circa 1989 'Biopace', which may explain why the chainrings were replaced with Campy 52/42.
The bike operates fine, so I've not had to swap out any parts. The rear dropouts are also spaced at 130mm, which if original, suggests that that it was built in the era of 8-speed gearing (although now it's 8/9/10 compatible). Rear hub is Shimano RSX FH-A416.
The frame serial # is YF98K00287, which I've triple-checked to ensure I have it right. It's stamped under the BB shell, and there are no other markings.

...drew a blank. I also recall finding another site that decoded the post-1974 serial #'s, but it didn't seem to work for me, and I can't find the URL again
There are some clues on the frame. The head tube logo and a decal on the seat tube suggest that it's an original England-made frame. The down tube contains a decal indicating that the frame or parts thereof are made of '4130' CrMo steel.

Per above, the serial # is the only visible stamping on the frame. The only remaining decals are the 'Raleigh' and 'R-100' on the down and top tubes respectively and a 'Raleigh England' decal on the seat tube.
Are there any other sites/resources or clues I can find from the actual frame that would help confirm its year of manufacture?
TIA.
