Para, that was my original thinking. See the Reilly line for the latest received from Holt's which pretty well established it was a pinfire, appropriate text below:

I asked Holt's as time permits and for academic purposes only to try to determine where both these serial numbers are found. Holt's send the response photos below. Clearly this was an early pin-fire, 10448 being found on the water table/action flats and on the barrels. 20320 is found on the tang behind the trigger guard, no doubt added when it was converted to Center-fire. 20320 would date to 1876. 10448 would date to late 1857 only 10 numbers earlier than mine. The name/address on the rib was also changed when it was converted.

What I was trying to see is whether it had the Berringer rising bite on the action flats. . .can't see from the photo above but what little you can see of the lump seems to resemble the layout of 10456 here: Of course, it's possible elements of the action including the lumps were changed out when the gun was converted to top lever.

A couple of posters wanted to see the lumps and barrel flats of 10456 (number December 1857) pictured above. Holts had kindly provided them.
