What's the difference between the standard Jr gentleman and the upgraded version, particularly in terms of bushing size?

I have a collection of unlabelled bushes that I bought with a mixture of pen kits which I'm trying to sort out.

And is the assembly pretty much the same?

Thanks #newbie

There is a phone app (Bushings and Tubes) that the IAP (International Pen Turners) have for a buck that tells you the tube sizes and bushing sizes for an awful lot of pen kits. They are updating it as it is a couple years or so behind. There is an iPhone and Android version I believe.

I use the IAP chart.....downloaded and printed out....old skool yes but when the WiFi goes down it still works!!
I think the main difference between the gents is tube length.....I have some pre cast blanks all jnr Gents and some are longer than others, but I use the same bushes:thumbs:

THe "upgrade" was simply a change of tube diameters a while back. The old version used to use 25/64 and 15/32 drill sizes, and they moved to slightly larger tubes which now use 10.5 and 12.5mm drills. I believe it also overcame the inability to use normal cartridges, which was a wee bear trap that used to exist in the old version.
