Dunno how can tell cones loose from photos. The cluster seems to have 31 teeth cf 32 normally. Would expect less but different pitch can be used for replacements.
(I have encountered loose cones, one with the splines all sheared off! Dunno what the symptoms are in car but could be curious. What mystifies me is that with most cars with similar synchro there is nothing to prevent the hub migrating after engagement so the other cone rubs. Maybe it often does. Maybe why made of bronze. Maybe why RNs often relatively fast. The Austin box is robust, well made and long lasting; the cones and ridging of the input gear bore probably the main weakness to reasonable mileage. No fragile inter gear thrust washers as plagued many other makes.)
