Need new cocking plate

Hi guys,

Wondering if anyone could help & lemme know where I can buy a replacement cocking plate (#45 on the diagram). Or perhaps a whole new breech assembly if the spare part is not available for sale. We don’t have any Cricket dealer in Asia, let alone Vietnam, and getting the right export papers to send this back to Czech (where I bought it) for repair is so much of a hassle, not to mention the shipping charge would be like half the cost of the cricket ;-(

Thanks very much in adavance !
