We speak from years of personal experience of frustration, disappointment and time wasted finding relevant quality militaria collectables. We can change this with a new solution.

We decided to develop a service dedicated to affordably sourcing quality militaria from multiple trusted sellers – where:

  • We never ask buyers to pay any additional charges
  • We offer free membership and unlimited militaria listings
  • We provide flexible selling options (auction or buy now)
  • We deliver expert marketing to attract worldwide buyers to sellers
  • We enable buyers and sellers to trade on one, easy to use militaria website

In 2022, Collexchange was launched -
a platform that will simplify and centralise the buying and selling experience for militaria enthusiasts – bringing collectors and dealers together on one auction website.

Keir has combined a busy and successful career with a lifelong passion for collecting quality militaria. With Keir’s particular interest in 18th and 19th century Scottish militaria, he believes collecting militaria is a rewarding experience because of the fascinating history that can be explored and the connection in owning a genuine piece of history.

With Keir’s personal experience as a buyer and seller – he has spent endless hours trawling dealer websites and auction catalogues – and endured the escalating commission charged by auction houses.
