Matchbox is no longer producing scale models long time ago. Most of Matchbox products are 1/76 scale, although some vehicles,just a few, are true 1/72. Almost all the vehicles range have been released also under Revell brand. I recently heard about a new release of figures sets also by Revell, we will see.
Original Matchbox products are hard to find, but time to time some appear on Ebay.

For a comprehensive list about Matchbox’s scale models in 1/72 scale check Henk of Holland site here

For figure set review we outstanding recommend Plastic Soldier Review site.
