Mauser HSc firing pin

I need information on a Mauser HSc serial 792***; army issue (?) as number 135 is stamped on one side of trigger guard. Condition is very good and 85 to 90% finish.

Need a firing pin as the tip has either been broken off or ground off. Will the firing pin of HSc and HSc Super interchange? Have found one for the Super but none yet for regular HSc. Any suggestions for a source?

Thanks for any help
