Having made two Mountfleet kits perhaps I can make some comments about them. In general the glassfibre mouldings are good although the superstructure moulding on the Cruiser had some flaws, it looked like the mould was past its best in places. These flaws were easily repaired however. The white metal castings again were generally good but a few were poorly moulded, Mountfleet are good at replacing faulty or missing parts. The ply parts printed on sheet were accurate and fitted well when made (more than can be said for some). The full size drawings were good and could be used to measure for the placement of parts although labels said not to scale, they worked well. The written instructions are basic, a few photocopied sheets that do not add much to the drawings. Both kits (ST Cruiser and Lighter No7) however turned into good models. There are build threads for both of them on this site.
