40X rimfire parts are not in abundance it seems. On occasion firing pin assemblies are listed but usually fetch as much or more than a new one from Kiff. Front half of bolt and extractors rarer yet.

@OP: please forgive the mild hijack.Which style bolt handle are you trying to get and does it have to be original or is aftermarket ok? I have a few bolts and may be able to help with a complete bolt. Wayne
