In regards to the Bronze bushings, The bronze bush is pressed into the carrier and the Blade bush is Mild steel.
Yes they used bronze for this specific purpose, just like You would use graphite to lubricate. My reason for use of brass is easily obtainable, low use, strong and a perfect ID/OD. If brass is good enough for a replacement small end bush, then I'm more than happy to go this way for low use Restorations, than to have to locate, ream, or bore a bronze bush.
In regards to ease of change for repairers, absolutely! but as I stated, once the bush has been replaced and new bolts fitted, then it will be years before a bolt head would be irremovable.
The main aim of using this style by myself and other restorers is purely for originality, and highlights the procedure for correct replacement of the complete blade bolts and bush for those who've not seen this system. So Its difficulty to change in comparison to the later style system is irrelevant.
Good score Paul.
These are the later blade and bolts to suit your Specials blade carriers( second gen carrier type) and later Styles. And yeah later packaging, but still quite early.
Just curious, what carrier is your Roto 3 running? It should be the later type, but with your serial no so low id like to see for certain.
A quick off topic...I missed a Model 4 std with a 130,000 serial yest. It would have to be the earliest Non Auto Ive seen. Not much gap when my latest recorded auto is 128,500. Would have loved it as it confirms yet again the Autos true end.
