@henrylr I understand that you're going to sell this trumpet and want to know if what you have on hand will suffice, as opposed to having to buy an additional product. Considering the condition of the horn, wouldn't it be best to sell it with the proper lubricants? Never mind that the new owner may decide to clean it out and redo all the lubricants, and never mind that buying the right slide grease will diminish your return on the price by about ten dollars; it's just good practice to sell any merchandise without undisclosed issues or cutting corners. Besides, you'll have the slide grease to use on other instruments.
