@Phil GErgo whist the cast A chair is correct, its only strictly correct for a few short years after of the adoption REA design concept.
Well that's broadly true, but because something is introduced doesn't mean all track is immediately renewed. On main running lines renewals would be typically at around 15-20 year intervals. On secondary and branch lines much longer. For sidings and yards probably never -- many of those would still have had pre-grouping track with loose-heel switches to the end. And cast A chairs.
For this reason I thought you were keen to add the slab and bracket option.
The reason for wanting to do it as soon as possible is to prevent being continually asked about it! Especially by folks who regard it as an error. I had over 10 years supplying model track as 85A Models back in the 1970s and 1980s and I think I know the minds of modellers quite well.
For amusement have a look at the slab & bracket chairs on the Finetrax 00 and EM kits (I don't know about P4) -- the through bolt has a bend in the middle! Wayne can sleep easy -- no-one else will notice.
