Anybody recognize these old ones, maybe Centuri?
 

These are old ones in my fleet but I don't remember their names.

The white fins/green body/gold nose rocket was built in about 1985. I seem to remember it being a Centuri kit, roughly equivalent to an Estes Alpha. It is BT50 diameter and 15 3/4" long.

The green fin/purple body/green nose rocket I think was built about 2000. I think it is a Centuri kit also, maybe a Firebird but I can't find a photo of a Firebird to compare with. It is BT55 diameter and 23 1/2" long.

The first one, if it is BT-50 in diameter, may be the Estes Antares #1276. Have a look HERE... The closest Centuri design was the Aerobee 500 (AKA Aerobee 350) #KC-5
[LINKY] .


SEMROC has the Centuri design as a RetroRepro kit [LINKY]...


The second one looks a lot like either the upper section of the Estes Vigilante #1278 [LINKY] , or the Estes Comet #1368 [LINKY]. Both were essentially the same rocket, with the Comet being sold only as a single-stage model sometime after the Vigilante was dropped from the catalog.
