Thus far this arm is the sole unpainted hardcopy representation I've been able to acquire for the produced Kalibak action figure, which was released in 1985 as part of Kenner's 2nd series Super Powers action figure line. Of course, unpainted parts exist for an earlier unused Kalibak design as shown here. A single arm isn't super exciting, but when added as part of a figure prototype series it gains additional meaning. This is especially true where, as in this case, the unpainted hardcopy stage would go unrepresented without an individual part. I enjoy collecting unpainted hardcopy parts since it's sometimes possible to complete an incomplete hardcopy when complimentary parts surface through various sources. Plus, there's just something I find visually appealing about dynacast!
