The model 36 was made 1920-1927 and was termed a garden gun. It could shoot a rimfire long, about 1.8" long with a 1/4 ounce shot load. It could also shoot a 9mm rimfire short or rimfire ball. If your 2 boxes of ammo are original Winchester manufacture from the 1920's and in good shape with original boxes they could have a high value from an ammo collector. The rimfire short and ball may be a bit more scarce than the rimfire long. Whether this ammo value is greater than the gun itself, I doubt, but condition affects the value of a collector gun alot. I believe Fiocchi still makes the little 9mm shotshells. There were a few other foreign gun makers who chambered their guns for the 9mm also. The model 36 is seldom seen, they only made just over 20,000. I have shot a model 36 and it did a number on English sparrows with the #9 shot rimfire long.
