Mark the date as unknown and keep confirmed contextual clues in a separate note.

Begin with the real constraint
Mark the date as unknown and keep confirmed contextual clues in a separate note. The aim is a small setup you can actually complete, not a larger collection of equipment. Lay out what you already have and notice the step that creates friction before changing anything.
Check the fit before going further
A partial decade can be useful if supported, but a confident invented date makes later correction harder. Conditions and specifications vary, so treat this as a question to verify with the relevant maker, venue or source when it applies. A quick trial with the actual objects is more useful than a promise based on a photograph.
Finish where the next session begins
Invite a relative to add context only if sharing the image is appropriate and permitted. Take a moment to check that the result is accessible, safe for your situation and simple to repeat. If it still feels cumbersome, reduce the scope before adding a new purchase.
