Herters was an importer headquartered in Minnesota from the early 1960's to 1979. I don't know of any way to find the actual manufacturer, but it is probably a close copy of some Smith & Wesson model, so a gunsmith could look through his spare parts bin and maybe come out with a pair that would (or he could modify to) fit.
J.P. Sauer was making some handguns for Herter back in the 60s. I have Herter 44Mag SA made by Sauer.

Herter's sold various maker's products with their name on them.
To determine the year of manufacture for your Herters recurve bow with the serial number 90859763, you would typically need to consult specific Herters serial number charts or resources, as the company used various coding systems over the years. Generally, Herters bows were produced primarily in the 1960s and 1970s. If you can find a serial number chart specific to Herters, it may provide a more precise year based on your serial number.
The value of a Herters Model U-9 .223 rifle with a Herters scope can vary significantly based on its condition, age, and market demand. Generally, such rifles can range from $200 to $600. If the rifle and scope are in excellent condition and have original packaging or documentation, the value may be higher. It's advisable to consult recent sales or an appraiser for a more accurate assessment.
It is my understanding that Herters only made rifles in the mid to late 60s and were sold mainly via mail order direct from them with a few stores selling as well. The Gun Control Act of 1968 pretty much marked the end of Herters rifles.
