I have a similar post going below you (model 36, D.O.B. and rebluing). The guys advice not worth the money to reblue. I did some check and S& W gets $190 standard blue, $235 polished blue and $145 glass bead blue ( a matte) You can ship direct without a FFL just pay shipping cost.
I found a gunsmith 10 mile from me
WWW.gunblue-homestead.com off the gunsmith page of this forum
He is $135 matte, $155 factory blue and $ 185 high polish. I am going with him because of location and price.
Hope this helps
