Have you ridden it yet with saddle adjustment? One guess, and it is a guess, is that the post is not giving a full range of adjustment because the saddle is also as far forward as it can go. A couple millimeters backwards and it might adjust fully. If I'm wrong it was still free and takes one minute. It is only a little down in front now, it could be enough.
With a full profile photo the other item that is visible is you have one long stem. That is at least a 10cm extension and it could be 11 or 12. The bar and stem are Sakae, so the clamp diameter is 25.4mm. That is the most common size in any vintage scrap pile. You won't likely find exact same style in a short stem, you will find Sakae/SR. I have both a 50 and a 60 sitting here but unfortunately they have both been converted to French. And they are so common it would hardly be worth the cost of shipping. SR stems in 50 and 60mm are just plentiful. If you can't find free, don't pay over $10. You'll be 2 full inches closer to the bars, the bike will be quasi correct/original, only cost is new tape. I'm thinking the saddle is all the way forward because the handlebars are just too far away. The common old SR stem was massively strong, perfectly trustworthy 30 and forty years later. And the basic stem was considerably taller than the racy stem you have now. You might not even need to go all the way to a short stem, if the current stem does measure out to 12cm, an 8cm replacement could be good enough.
I am seven years older than you and 2 full inches shorter than when young. So the saddle is down and the stem is a little shorter. Other adjustments? When I'm 80.
