The Rosebud Kitmaster and Airfix railway & Trackside ranges were sold to David Boyle of Dapol Model Railways and the tools were transferred to their premises in Winsford, Cheshire (later in Llangollen, Clwyd and now Gledridd Industrial Estate in Shropshire.

The range consisted of 34 kits of individual locomotives or carriages, a model of the Ariel Arrow motorcycle, the "Fireball XL5" rocket, parts to motorise the railway kits (using a motorised box wagon supplied pre-built, or a motor bogie) and three railway presentation sets: All of the moulds for the kits produced by Rosebud Dolls Ltd under the Kitmaster name were sold to Airfix Products Ltd in 1962, and later in 1982 all of the surviving tools were sold to Dapol Model Railways.

However, not all of the kits were passed over and several were destroyed by General Mills / Palitoy at the Glenfield warehouse where they had been stored following the liquidation of Airfix Products Ltd that year.

Prices of unmade kits for the rarer models, such as the 00 gauge LMS Beyer-Garratt locomotive, can reach as much as £100.

Before its demise, the company announced the introduction of a number of kits that never knowingly[clarification needed] entered production, including the LNER Flying Scotsman, Southern Railway Class USA Tank engine and Canadian National U-4A.
