TO39 transistors

Just stumbled upon these. Anyone like to take a punt on whether they are the real deal. Would anyone bother to fake these?

I gave up on eBay parts when I realized I could usually find modern versions of the same parts on Digikey for the same (or lower) price.

Here is the plastic case alternative for just $0.14 each. Obsolete like the tin can version but much less risk with Digikey stamp of tracking and tracing approval.

Just to stock spares for my 50yo 'scope. I don't know if it uses those exact ones, but I noticed a few TO39's from that seller, so s/he may have the ones it does use. Just one of those things I keep an eye out for. I find it sad if I have to resort to modern substitutes.

let me know if you have part numbers. I have a bunch of old stuff that my kids will just toss when I kick.

Thanks for the offer! But I fear postage might be a bit much :(
