SMC-A 50 2.0 for parts

Hi
The A-connector on my A50/1.4 is missing, after an unsuccessful trying of lubrication of the aperture ring. At first just the spring under the pin but now both the pin and the spring were missing.
If you have an A50/2.0 lens, or any other Pentax-A lens that you want to throw away, will you please send me a PM? It will be even better if you want to disassembly the mount and mail me the pin, holder and the spring.
Thank you for looking.
Graham

Is this what you're looking for? I know it's from a Pentax A lens, probably a 35-80mm.

I know it's not from an A50 F/2 because I've never had one.

In the photo, the black marks in the background are millimeter marks. The whole thing is about 5mm long.

I can see the pin and the spring, but am not sure what the "holder" mentioned in your post looks like.

Drop me a PM with your shipping address if that's what you need.

Thank you very much, SOldBear!
That is right, these are the parts I am looking for. When disassemble the lens, the little spring was missing. So I tried to attach something else under the pin so it could still contact the camera. Unfortunately, I broke the "holder" that keeps the pin on site. see the pictures below.
Do you happened to have the two little things with the pin?
Will PM you.
Thank you!

@grahame, if SOldBear's parts do not work for you, I have an SMC-A 50/2.0 that would make a good donor. It's in perfect mechanical condition, but the front element has some markings on it. You are welcome to it, just pay for shipping.
