The last thing to note is the 3 cones are identical in shape and size but obviously different generation nose cones. All and all a great bring back kit. More to follow.
BTW I've noticed that there is a length difference in the different generation nosecones.
I've got a PNC-60AH injection molded from a Estes Omega ca 1971 in a sample that was sent here in China. My measurements has it at 6 5/8" long
I've got another PNC-60AH from an Omega produced after the switch to blow molded here in China. It measured out at 6 23/32" long. A difference of 3/32".
Regrettably, I don't have a modern PNC-60AH to measure here.
To measure the nosecones, I put them in a body tube, then hold the body tube in a piece of aluminum angle, I push them against a flat surface, mark where the nosecone ends, and measure from that.
I'll note that there appears to be discrepancies in the lengths of nosecones in the Estes Catalogs. In 1971-1973, the
BNC-60AH was listed as 7 1/4" long in dimension 1 (exposed length), by 1974 it looks like the error was caught and the
BNC-60AH was then listed as 6 5/8" long (the PNC-60AH wasn't listed as a separately available part for purchase during those years). The
PNC-60AH appears in the 1975 catalog as 6 5/8" long despite actually being longer.
