The best replica is the one I made.
I took care about all details diameters and curvatures,however I spent about 20 hours with machining and polishing.
Internal part of my pommel is really different,because of special use.
However,when screwn on the booster,it' as close as possible to original.
I don't leave room when I screw it,because I have made special drawing mentionnig why it's less or more screwn on booster,for cooling internal energy cell controller,same thing about the cap,that's why on "tunisia" cap is missing,to bring more air for cooling....haha.
Then I think about the Russrep:
measurments are quite same,except the first rim near booster,too long,4,5mm instead of 4 mm,some curvatures are wrong,and some details are missing.
negative radius instead of positive radius;a 0,3mm rim to;internal rim too;cubes radius but these details are really ennoying to reproduce,and would be really explensive to sell...
Internal is very different to original,cap is really different too.
Polish is not very good,but I think it's the best replica available for the moment,for a reasonnable price.
Imagine if Russ was obliged to spend 20 hours for a pommel,what would be the price....
Original part is cast,and cast items are really difficult to reproduce by machining...
good,it's possible to choose version,by reversing the cube section.
About Roman's I don't know,sems it's not so accurate,even it's reversible.
I don't really want to spend 80 $ for it,but if someone has good colose up pics,I 'm interested in!
Modern AS is not really nice,I think it's far better to use a russrep,even a romans than a modern AS handwhell.
