There are lots of plans out there for the old Eureka and KYO kits. There ia a KYO kit of the B-36 on E-Bay right now. Goes off tomorrow I think.
go To the bay, search for B-36 and it will come uo (amidst a lot of bras in 36B sizes)
Last time I looked this morning it was still at a reasonable price in the low $200s
