A friend gave me his piccolo trumpet to see what I could do with it. (Oswal India, nuff sed)
Pulled stuck slides, easy enough, removed valves, casings numbered 1 2 3 4, Valves 2of numbered 1, other 2 no number,fun to sort out on reassembly, valves appear to have been greased, very sluggish.
2 leadpipes, assume Bb and A, both receivers just parallel tubing, Bb the mouthpiece goes into the start of the leadpipe and is firm, in A pipe does not reach leadpipe and wobbles.
This is as far as I have gone, the next step is to give it a good cleaning and then reassemble paying particular attention to valve alignment. I have Blackburn Bb and A pipes that will fit.
More to come.
Regards, Stuart.
