A retailer on ebay is selling vacuform canopies from a new company called AP Model. The current offering is a 1/48 scale canopy, turret and landing light clear part set #APV48003 priced at $2.65. The seller states his supplier made the set to fit the 1/48 MPM Classic Airframes kit. (I can find no information on a 1/48 Boulton Paul Defiant kit from MPM.) The quality of the parts is claimed to be good, similar to Pavla and Rob Taurus canopies.
I have found no information on AP Model or a review of any of its products.
If anyone has information on this company and its products please let me know.
