The answer is an unqualifed yes. The conversion was often done with the flintlock being replaced with a percussion cap system. The end result would be a .69 caliber smoothbore musket, some with shortened barrels and some unaltered barrels. For ammunition these conversions would be loaded with "buck and ball" a paper cartridge holding a .69 caliber ball and two .33 caliber "00" buckshot". Extremely deadly at short range. Ones with shortened barells were often carried by the Confederate cavalry.

To determine the choke of a Springfield Model 67 shotgun, you can measure the constriction of the barrel at the muzzle. This is done using a choke gauge or calipers to measure the inside diameter of the barrel at the muzzle and comparing it to the diameter further back. Standard chokes include cylinder, improved cylinder, modified, improved modified, and full, each corresponding to specific constriction measurements. Additionally, you can test the patterning by firing the shotgun at a target and assessing the spread of shot to gauge the choke's effectiveness.
I have a 12 ga 67F, 28" modified that I bought in a pawn shop in 1973. Still shoots great after thousands of rounds. I paid $65 for it then.
The Springfield 410 model 67b pump shotgun is valued at $200 in fair condition. In good condition, it is valued at $300.
My first shotgun was a springfield Model 67 around 1973-74. I dont know about the "E" but mine was a 20 gu shotgun
Your weapon is not a flintlock but a percussion cap shotgun rifle made by GG Julcher of Philadelphia PA from c 1840 to the Civil War. It is an unusual weapon as the shotgun lock (Hammer and cap) on the left side is upside down, an extremely clumsy solution as the cap tends to fall off.
Contact springfield arms and ask them. They should be able to look it up and tell you.
