Stevens Marksman 22lr

Good day everyone. I'm new to the forum and Savage Arms. I have bought a few different models and I can say I love everyone of them. From the cost appreciated ones to the higher end models. I recently purchased a Marksman 22lr and it doesn't have a hammer spring. All the sites I've googled were out of stock. What about the after markets? Would any other models have the same spring? Last question, would anyone here know the length of the spring? I would really like to get this old girl up and running. Thanks in advance
