You mentioned that you used some original comps - you wouldn't be kind enough to share them with us would you?
I have been making a few more rockets for bonfire night -

Barium Nitrate 50
Potassium Nitrate 10
Dark Pyro aluminium 15
Aluminium flitter 10
I haven’t had much luck with it, as it burns very hot and will slag the nozzle rapidly causing the tube to catch fire. It may have been one of those fountains that were manufactured by simply pouring the comp into the tube, then sealing it with the resin and saw dust method. This comp will require a very hot prime to ignite it if you wish to use touchpaper.

Here is a nice formula for the carnival spray that does not have too many ingredients, this particular formula is Astra's;
Charcoal 20# - 8 oz
Charcoal 60# - 1lb 8 oz
Kno3 crystals - 8lbs
Sulpur - 2lbs
Titanium fines - 2lbs
Gunpowder meal "A" (very fine meal) - 2lbs
Gunpowder F.0.A (around 50#) - 9lb
I don’t recommend making the quantity describe here but adjusting the quantities into parts or converting to grams to make small batches. It does not burn too fiercely and requires consolidation with either ramming or pressing. The effect is very nice shimmering orange sparks with bright white titanium sparks that attain I height of about 10ft, interestingly the cost to make the quantity described (11.567Kg) was £6.83. Sorry for the mixing of units, the formula itself is typed but there are hand written notes on it detailing price, final quantity manufactured ect. Enjoy

Most fired well, although I had some issues with touchpaper based ignition.
I sometimes sneek a stick of black match into the comp and let it be twisted into the touch paper.
Although not authentic this usually ensures ignition...
