Your question has probably not been answered because the serial number 72xxx was made in about 1930 BUT the Sport Model Woodsman with 4.5" barrel did not make its appearance on the market until 1933 around serial number 86000. So this needs some clarification from you before an intelligent answer can be given.. It is quite possible that the original 6.625" barrel was shortened or re-barreled with a short barrel and the gun was not made as an original Sport Model Woodsman. The phrase "early knurling pattern" indicates that the gun has had the barrel replaced. If by knurling you mean the checkered area on the backstrap, then for sure you have a re-barreled gun because all Woodsman Sport Models were made with horizontal, parallel lines on the upper backstrap so the gun cannot possibly be an original Sport Model. Most important is the need to supply a detailed description of the condition of the gun, especially the amount of original factory blue finish. The value range can be as much as $1,000. depending on the amount of ORIGINAL factory blue finish remaining. If you want to email some good clear photos fothe gun and its stampings I may be able to give you an accurate evaluation. But with the information given , no practical figure can be arrived at.

The pattern for barrel racing is simple, and goes like this: 1. leave the starting gate and head towards the far side of the barrel to the right. 2. go around the barrel to the right and head up the the right side of the barrel that was to the left of the starting gate. 3. go around this barrel to the left, then head up to the right side of the point of the triangle and go around to the left. 4. race to the finish line!
Pattern is dictated by the amount of choke on the barrel(s)
the figure eight
A shorter barrel creates a wider shot pattern.
Firing lead shot through a slug barrel will not damage the barrel. The rifling will distort the shot pattern and you will get less than desireable results.
Barrel racing got its start with the Women's Professional Rodeo Association in 1948, in Texas. The course was originally a figure-eight pattern, but was replaced with the more difficult clover leaf pattern.
A standard barrel pattern in the WPRA is as follows: 60′ from the score line to the 1st and 2nd barrels 90′ from the 1st to the 2nd barrel 105′ from the 1st and 2nd barrels to the 3rd barrel This is a large pattern and many times it won't fit in smaller arenas. If you have to decrease it, do so proportionately. Hope this info helps answer your question.
the barrel is narrowed at the muzel for a tighter shot pattern.

the left barrel shoots a tighter pattern than the right side
the barrel is constricted at the end to make the pattern of shot flow density wider or tighter. Usually from cylinder up to full choke
Years ago with the old type of powder I would say a longer barrel would be an advantage, but with todays hotter , quicker burning powder you do not need to lug around that 30" barrel for the sake of hold a tighter pattern. I found that out when I bought a 10 gauge with a 30" barrel and realized I was being outshot by the magnums with 26" barrels and less.
In a standard clover leaf pattern, there are 3 barrels.
on a normal pattern, it is usually 16 seconds or less.. :)
If you mean a muzzle brake or barrel weight, yes. It can change the vibration pattern in the barrel when the rifle is fired, changing the point of impact. Anything added to a barrel, such as a sound suppressor, will affect the zero.
The choke is a way of narrowing the barrel. It is designed to keep the shot in a tighter pattern. A full choke is supposed to increase the effective range of the weapon.
A damascus barrel is a barrel made of damascus steel, which is steel produced by hammering two different steels together. The twist refers to the pieces of steel being twisted while they are hammered, which produces the distinctive pattern on the steel.
They came in various barrel lengths and choke combinations. If it is not marked on the side of the barrel, you will have to pattern the shotgun to determine the choke
In barrel racing the rules are that you must go in a cloverleaf pattern. The pattern can be run with 1 right turn and 2 left turns or 1 left turn and 2 right turns. Failure to complete the pattern results in a no time. If any obstacles are knocked over the rider gets a 5 second penalty.
No. The lead of the shot is MUCH softer than the steel of the barrel. However, if you have a RIFLED slug barrel, expect poor accuracy with any shot load- the rifling will make the plastic shot cup spin, and as it leaves the barrel, centrifugal force will make the shot pattern open into a "doughnut" shape.
A choke is a device placed on the end of a shotgun barrel that changes the pattern of the shot as it leaves the rifle.
It is called a choke, and is design to tighten the pellet pattern.
The Choke of a shotgun is the amount of barrel restriction at the muzzle end which affects the shot pattern. A full choke will keep the spray pattern of the pellets closer together farther out than if the barrel was not restricted at the muzzle. If there is no restriction at the muzzle, the choke is said to be cylinder choke or cylinder bore.
