Jim, it is thought that Commercial Lugers between 75,000 (approximately) and roughly 92,000 were made following WW1 until about 1923 when the "Alphabet" Commercial Lugers began with a four digit number and the letter "i". The suffix letter "i" would make the beginning of the Alphabet Lugers start at approximately 90,000 although it's thought that production actually reached 92,000 before the suffix letter was introduced. It's interesting that the five digit Commercial Lugers became known as the 1923 model while the later-production "Alphabet" Lugers are commonly called the 1920 model. While some post-war Lugers undoubtedly used surplus parts, the Alphabet Lugers almost certainly were new manufacture. The Alphabet Lugers are very nicely made of quality materials.
