In a geography where the electronics component industry is extremely hobbyist-unfriendly (e.g. India), questions around salvaging parts, and any useful answers that result, are invaluable. I would dearly like to see the question referred to being reopened, as it is one that every electronics hobbyist in places like India should be directed to.
On a similar note, "if it doesn't have a datasheet, don't buy it" is equally unhelpful for an audience in my geography: Every week, I struggle to source datasheet-supported parts, without being able to meet the MOQs or shipping costs for international ordering. Locally, I am constrained to whatever my city's "electronics street" shops will sell, and what very limited and highly overpriced parts the few online stores offer. I would challenge anyone to source 5 red LEDs with a known part number and datasheet in India, let alone a solenoid such as you have asked for, with known parameters.
Either this site is a global resource, in which case salvaging and making do with sketchily supported or obsolete parts are crucial questions, or this is a very USA/Europe oriented resource, in which case someone needs to propose the equivalent of "Stack Overflow in Swahili" on Area51, for EE.SE too! (I certainly hope not!)
