1864 Henry Carbine Prototype new style magazine tube

[Henry4440]

J.G.Bilby wrote in his book:A Revolution in Arms, that Winchester forward a prototype carbine to the Ordnance Dep. in Jan.1864.Unfortunately, the gun,hastily assembled and chambered for a new,longer .44 cartridge with greater powder capacity, did not prove satisfactory to Maj.Dyer at Springfield Armory..............In addition, he believed that the internal parts were easily 'disarranged' and the new style magazine tube was inadequate and could be removed from the gun and lost.

What that this mean?Was that an magazine tube like the '66 had?
