H&R Auto Eject 32 S&W CTGE

Hi, Found this forum while trying to find info/parts.
Sorry, I don't have any pictures or know how to post them here.
Here is what is on gun:
Top of barrel:

Left side:
AUTO. Ejecting 32 S.&W. CTGE

Story is back in 1990's a family friend found two handguns when cleaning out an old house. She gave me both of them and I put them up and never thought about them til yesterday while cleaning out some junk in our garage.
My wife thinks it looks "cute" and wanted me to see if it could be fixed.

I found some threads, but can't find a diagram and parts listing. I went to a link found in one of the threads here but only part listed was grips. This one has a good set. Anyway, I know it needs a trigger and guard.
Any assistance and guidance will be appreciated.
"Thank you!"

 

I don't know much about guns, never looked at "top-break" before.
But found picture in older thread with info on removing cylinder so started by removing it and cleaning it, today.

Noticed I didn't post serial number in first post: 148240.

Gone to link in others post to "Numrich" for parts but I still can't figure out which Schematic or parts list I need.
I really would appreciate any assistance or guidance that could be provided.
Thanks!

 

WHSmithIV, "Thank you!" for replying and the information. I did not realize the gun was that old til read your post. Never thought about it would need black powder. Maybe, that's why it was so dirty between the cylinder, ejector and frame. It took acouple different soakings of cleaner with several times brushing before could get it clean. The rest of gun was already clean, even barrel was already clean.
Pictures, I read the forum info posted about placing pictures here. Seems easy enough but will take me a few days, need to find a camera.
"Thank you!"

 

Sorry, It took awhile before found camera. Finally got some pictures. They are not very good but best I could do.

I checked Numrich for parts. But I could really use assistance on which parts list I need. Like I posted earlier I know little about firearms but like to try to repair it.
"Thank you" for any assistance and advice ya'll might offer. I do appreciate it!
