The complete statistics for those weapons were never presented publicly. Each creature in the Chainmail game had a Stat Card that was included with the miniature. The card documented the combat statistics of the creature, including even more abstracted Health and Damage scores, plus movement rates and ranged weapon ranges in inches, but did not include price, weight, etc.
The Chainmail game was discontinued in 2002, and the stat cards were not distributed digitally, except those for unreleased models (last few models of set 4, all of set 5). The successor, D&D Miniatures, had digitally released stat cards and rules for using some of the minis from Chainmail within the D&D Minis' League play.
None of the 4 model you're interested in are included in the League sanctioned list, and even they were removed in later League lists. The successor to League D&D Minis is D&D Mini's Guild, whose original and revised cards don't appear to include those 4 cards. If you want a Stat card, you appear to need to purchase a complete mini or Mordengard set 3 or 4 boxed set. They're hard to find.
The Chainmail Core Rulebook, which was released for sale as a digital download after the game was discontinued, has a section on p.117 that says
... All Chainmail models have D&D statistics, and almost all of them have their statistics published in guidebooks, in Dragon® Magazine, and on the Wizards of the Coast® website...[which] has “battle sheets” for many Chainmail models. Each one-page sheet gives you all the information you need to run a Chainmail model as a D&D monster or NPC...
If you want to use a Chainmail model in a D&D game and don’t have a battle sheet for it, you can use a quick-and-dirty system to convert its health and damage scores to D&D statistics. For each point of the model’s health, roll 2d4 for hit points, and for each point of damage (melee or ranged), roll 1d10. If you’re feeling industrious, you can also adjust some of the creature’s saving throws up and others down instead of using the single save number.
The rest of the section details movement rates, and D&D 3.0 rules for the space of Large (Tall) or Large (Long) creatures, then goes into using the Chainmail rules for command and morale.
The next section on pp.118-122 discusses converting D&D creatures and characters for use within the Chainmail rules, and the only thing it says about weapon ranges is
For thrown weapons, give the model a 6˝ range. For projectile weapons, give the model a 24˝ range. Give a model with a ranged weapon either a one-shot limit or no limit on the number of ranged attacks it may make. (Keeping track of ammunition is a hassle, but remembering whether a model has
used its single ranged attack is easy.)
These rules might extrapolate in reverse, but the Battle Sheets presented don't detail such.
Dragon #291, which has a section on Chainmail's Mordengard dwarves, has no details to offer regarding the stats of these minis.
