Hi, I have a LION 5" gauge loco that I am restoring . The main item is the fire ash pan is missing . I am hoping that one of you nice lads can let me know the size of the ash box including the depth .Also does the retaining pin got through the lugs on the bottom of the fire box, or if its very shallow would the pin go underneath the box.I don't think I could make one by myself as I am now 86 and 3 quarters Thank you in advance..Kind regards Alan
