I'd hardly call your gun "cobbled together"! It's only had a barrel change and the usual grip change. You'll like some later vintage Magnas or targets a lot better anyway for a shooter.

SERIAL # LOCATIONS: To confirm all parts are original, one can check for the 6 (or 7, on Triple Locks only) matching serial # locations for fixed sight pre war Hand Ejectors and all post war Hand Ejectors thru ~1956 (and a few as much as 3 years later).
NOTE: Observing serial #s for accuracy or even existence, especially on penciled stocks, requires magnification, bright light, cleaning, and an attitude that it is there!

1. Gun butt – (or fore strap on I frames/single shots with grips that cover the butt)

2. Barrel - bottom of barrel or in extractor shroud

3. Yoke - on rear face only visible thru a chamber with a flashlight

4. Extractor star – backside facing cyl

5. Cylinder - rear face

6. Right stock only - on back, (except most post war target stocks because individual fitting not required); stamped, scratched or penciled depending on vintage and stock material.

7. Triple Locks only: rear side of middle lock cam plate


The notches in the barrel are very simple to cut/file with no precision dimensions. Once you have a mushroom knob, just file and deepen the notches until the knob clears when the cyl is closed.
