The Pulsar bow-tie is very available...I can certainly part with one for the price of postage and an envelope....I never throw them away...bit neurotic

The Sinclair: hmmm, that would be pretty rare. It seems to be the most commonly lost part of those, right along with the battery hatch proper - both are fairly "junky", IMO. And you will struggle with the dilemma caused by the soft, flexible plastic of the battery hatch: if you use a strong clip, the hatch will bend and want to push free of the case.

A weak clip will struggle to keep contact.

And that plastic is almost impossible to glue to - I think I had to resort to melting the clip to the back on the last one I fabricated.
Darn, you had to remind me that I have one of those (Sinclair) waiting for that also. Mint, boxed, paperwork - no stinking clip!
