Removing springfield trapdoor cleaning rod

[TrapdoorMan]

I would like advice on how to remove the cleaning rod from an 1873 springfield trapdoor 45-70. It's free enough to turn with my fingers but i can't figure out how to release it to remove it. Got any ideas. If you can't help me can you please refer me to someone who you think can help. Thanks.

(1) Remove the cleaning rod. On most arms, this entails pulling the tip of the rod away from the barrel to free it from the stop, and then forward. (on the M1865 it will pull straight out - on the M1866 and M1867 Cadet (lucky you!) it must be unscrewed before withdrawal). On the M1880 and M1882 TRB models, slide keeper (if present) to the left, press thumbpieces against barrel and withdraw rod. On the M1884 and 1888 RRB models, press on the checkered thumbpieces to withdraw the rod.

modestly pull the rod away from muzzle and simultaneously pull forward.

The first picture shows a groove below the retaining spring of barrel clamp, that has to be cleared first.

If the Model is a 1873, check the SN against the known "Custer 7th Army" confirmed issued SN list. You MIGHT HAVE SOMETHING!!!
