I think this is what I have - 1954 Gretsch Broadkaster "Bop" Outfit. Page 4 of the 54 Gretsch catalog.
The Hihat and snare stands, pedal (from what I can see here), the 3.5 inch cowbell and 7" woodblock with the combination block and bell holder and drums (14x20/9x13/16 floor and 5.5x14 snare) and K 15" cymbal (says medium weight 15 in description) are what I have. These items are listed in the left column. The K Zildjian - listed - is $33.....at today's dollars that's $221. The kit without cymbals was $435 as you can see.......today that would be about $3000. I think my 15"K may be 1945-1949 from the information I've gathered here.
The hardware case is a little rough - straps are gone but they can be bought online (steamer trunk repair website). The canvas cases are pretty bad but I will do what I can to save them.
I'm happy with the kit
