Excellent finds in such condition. The 3-detonator cylinder (No.530 or No.533) bottom right is Indian manufacture, detonators filled and cylinder packed at Kirkee, June 1961.
The cylinder (No.124) of practice detonators top left is a scarce find given the inter-war date and full intact contents - a photo of the igniters would be appreciated.
The cylinder (No.124) top right is marked TP for Temporary Packing, so there is no wooden block. The igniters were individually wrapped in greaseproof or shellaced paper, or cellophane.
