I have images of nearly all of the standard size EP vinyls. Can PM them if you are interested.
Some are here, but the Mirroman section is down:
http://mononofu.hp.infoseek.co.jp/museum/tsuburaya_ep/ep_main.htmlI've read that they were sold in 1982 (via Club Tokyo), along with the Ark and Orange vinyls. Later than I would have thought.
Tsuburaya Enterprise (aka, EP) was one of the 3 companies spawned when Bullmark went under (along with Ark and Orange). EP reissued a bunch of Tsuburaya kaiju seemingly at random. One interesting difference between EP versus Ark and Orange is that the latter two also sold new sculpts along with reissues of Bullmark/Marusan toys, whereas EP only sold reissues. I've always wondered whether these new molds were developed by Ark/Orange or whether they were in holding at the time of Bullmark's demise and passed on.
By the same token, there are some Bullmark toys that should have been reissued, but do not appear to have been produced. The above website shows them as blank spots, so I do not know if they were unproduced or just extremely rare. E.g., Dakron, Aian and Imbera from Mirrorman (would have been done by EP) and Bullkong, Bandera and Metalinome from Capt. Ultra (Ark). Some are even shown in b/w ads for the Ark/Orange toys. Anyone know? (Sorry, not to threadjack, but the thought crossed my mind while posting.)
