A No. 4 Mk I in its original military configuration can be more sought-after than those with modifications. This, in turn, might also affect its price (or at the very least, its speed of sale).
Manufacturer

Royal Small Arms Factory (RSAF) Enfield-produced rifles are generally more valuable than those made at other factories, such as ROF Maltby or Savage Arms. It’s due to their historical significance and quality control during production.
The RSAF at Enfield was the birthplace of the rifle, after all. It was founded to enhance the quality and reduce the costs of British weapons. This meant it used advanced machinery to produce high-quality, interchangeable rifle parts, surpassing the Birmingham-made muskets of the time.
Rarity
Some variants or production runs of the No. 4 Mk I are rarer than others.
Unique features or limited production runs can command significantly higher prices. For example, a No. 4 Mk I made by RSAF Enfield with a rare configuration could fetch over $500.
