Thanks for checking out our new site, if you have any questions about any of the 1919A4 parts listed in the online store, or 1919A4 linker? feel free to  give us a call at 513-535-4621, or Email. We try hard to keep inventory current. This is a family owned  business and we do this full time. Parts orders ship out most generally the same week, unless it is back ordered.  Tripods and items I make, may take a couple weeks.  Any parkerizing may add a few days also. Thank  you again for your business.
