I've recently acquired (on eBay, at a very low price) an Imai catalogue from 1982. As well as being fascinating reading, this answers quite a few of the questions previously posted on this forum about exactly what kits they produced and in what scales! The catalogue includes a whole range of wood kits - both plank-on-bulkhead and solid hull - which I've never seen or heard of before; as well as duplicating most of their plastic range in larger scales, their wood range included a number of unique subjects such as the early Japanese steam warship "Kanrin Maru", a Dutch state yacht, and the clippers "Flying Cloud" and "Thermopylae" (the latter being an accurate model, and not a slightly-modified Cutty Sark, for a change!)
I can't help wondering if the duplication of the same subject in multiple scales and materials was one of the causes of Imai's downfall! They made at least SIX different Cutty Sarks, not counting the tiny ship-in-a-bottle - two plastic and four wood (the 1/80 kit was also issued as a special edition "King" version with cloth sails, teak deck planks and extra brass fittings). Producing the Nippon and Kaiwo Maru (Japanese sail training ships) in both 1/100 and 1/150 scales in plastic was an even more bizarre idea, given the costs of tooling the moulds. Either scale produces a large and impressive, fully detailed model so I can't imagine they recovered the tooling costs of producing a new kit in a somewhat larger/smaller scale (not sure which one was first issued).
Despite their otherwise very high standard of historical accuracy, Imai also couldn't resist doing the "pirate ship" trick, reboxing their 1/100 Spanish Galleon with skull-and-crossbone sails and flags. This model, painted a dark weathered black, looks straight out of "Pirates of the Caribbean" despite being 20 years earlier!
One other thing to note is that some of their wood kits - the Charles W. Morgan, Nippon Maru, and Sir Winston Churchill - only have the box art in the catalogue, not a photo of the finished model; possibly these ones never got beyond the design stage, as I believe Imai went out of business not long after the catalogue was produced.
At some point in the next week or so I'll scan in the pages and upload them to Photobucket or similar (My own webpage may not have the bandwidth to cope with about 40 high-resolution colour scans all posted at once). For now, here's a list of the kits shown in the catalogue: (See next thread)
