With the serial number I could tell you when it was made, but I wouldn't be able to be sure of the generation as far as what it has inside without opening it up.
This is interesting information. Thank you for posting.
So if I were to buy an older Accurate reel, which is no longer made, I could very possibly be buying a useless reel if one of the parts were to break. Let's say, for example, the ARB had been upgraded and you no longer support of older model ARB.
I realize that this is true about any company selling any product, but if I bought a older model Shimano or Penn reel, the parts, weather new or used can still be purchased, because of the volume of reels that had been sold.
For example, I own a Shimano TTS50W. This reel was probably discontinued maybe 25 years ago, but I can still purchase some new, but mostly used parts.
Not bashing. Simply making an observation.
Smaller companies are better able to identify defects in their products, and quickly make changes, which is a good thing, but that leaves the owners of the older models out in the cold.
When companies like Okuma, make a defective product, they have a BIG problem. So they simply make a New model to replace the old. Shimano has done the same, but they call it an improvement or upgrade.
