Introduction and help with suffix identification

[Geladen]

Hello All,

I'm a 34 year old gun enthusiast/collector based out of Florida. I only collect military firearms with a focus on WW2. I recently acquired my first Luger. It's a byf 41 with a properly stamped fxo magazine with nonserialized black bakelite bottom. I bought it from the grandson of a US Army officer that graduated West Point in 1944 (would finish his military career a Captain), immediately was sent to Europe, and returned in 1945. Along the way, he acquired this Luger and brought it back to the states, so the story goes. It came with a holster and a second magazine that doesn't match the gun, but may belong with the holster, which I don't believe matches the gun based on my limited knowledge and research (will make another post for that). The gun, including the grips, shows up a little darker in these pictures than they really are.

I haven't fully stripped it down to check the serial numbers on internal parts, but all numbers on exterior match. I am having trouble confidently identifying the serial number suffix. I have included some pictures for reference. I originally thought it was a "f", but upon further research, I now believe it to be a "t".

Already planning on my next Luger purchase, which I would like to be a S/42 version.

Thanks in advance for any help.
