Best solution is to try to get a copy of the Estes 1974 Parts Catalog.

is this the same publication? http://www.oldrocketplans.com/pubs/...rts_Catalog.pdf |
Yes, that is the same publication.
|
It looks like it slides over a BT-60 (Estes)
|
thanks
thank you all for your help, when you look at the old prices don't you wish for a wormhole :chuckle:
|
Old prices of that 1974 catalog, yes; Old WAGES of 1974...dunno; the average middle class family with ONE full-time bread-winner had MORE purchasing power then. If wages actually kept up with productivity improvements and inflation, that should be possible now....reasons why not are numerous. The largest one is this supposed GloBULLization.
|
Minimum wage in 1974 was $1.80 an hour. I was making $2.00 an hour working 20 hours a week. Four hours a day for 5 days with week ends off. I could buy a lot of rockets back then and I did. Often I would save my money till the end of the month and buy out the store of rockets.
