Some new models have recently been acquired.
The BBW is a ready-to-run model available in 3-car packs. It is very nicely done, having some very fine detail.
The BBP is a composite kit comprising polyurethane castings, nickel silver and brass etchings and lost was brass castings. I believe all of the patterns for this kit were 3D printed then cast in polyurethane and brass. The detail in the kit is superb, right down to the rivets on the sides and hinges and padlock on the gas cylinder compartment doors.
