This item is for tracking of all individual pieces of Dwarven Forge terrain and accessory items from Master Maze and SciFi lines. This includes items sold as singles and small groups. With the exception of "Half-Size Bow Ties" all of the Individual Pieces were originally sold as part of larger box sets. This item is intended for when combining old sets (with bow tie indentions) and new sets (without bow tie indentions) so that the user can fill in the "half gap" created with the old and new pieces touching. As numerous items have been available for separate sale in the past and are no longer available the list of items given here may not yet be complete. 017-D3 6" long passage 018-DPT Set of 2 short passages with pits 018-E2L L-shaped passage with 4 traps swinging LEFT 018-E2R L-shaped passage with 4 traps swinging RIGHT 018-PTB Set of two 2" walls with pits 018-PTC Set of 4 floors with pits 018-R Wooden ramp with stone boulder 019-ARW Set of 4 arrow loop walls 019-ARW2 Set of 4 arrow loop passages 019-DFB Falling block trap 019-DSW Swinging spiked log trap 019-FLB 5 ton blocks, set of 2 020-CPF T-shaped cavernous passage with chasm 020-CPU Dead-end caves, set of 4 CA-O Small water tubs, set of 8 CA-X3 Small flat cavern rocks, set of 8 CA-X5 Cavern Floor piece C-block 2" x 2" floors, set of 5 I-Block 1/2 Half-Size Bow Ties (Set of 100) IND-UR Assorted urns and pots IND-CD Free-standing torches, set of 6 IND-CR Light barrels, set of 3 and crate stack MF Mermaid Fountain MM021-XSA Sarcophagus MM-025CLB Cavernous Lake Straight Bank Piece MM026-MBC1 2 x 2 Wood Floor (set of 5) P-block Red pillars, set of 8 SF-004-B3 6" Long Sci-Fi Walls (2) SP-block Spiral stair X-2/6 6" x 6" Square Floors (Set of 6) X2-block Floor tile, 6" x 6" (user summary, stock items and descriptions collated from publishers website)
