I found this example at a recent show.

The lugs have evidence of a history of bending, but overall the example looks clean.

Evidence so far available points to only two batches of cases ever having been made.

Case numbers between 7748x and 7825x, plus between 8209x and 8289x (where 'x' is a single digit) are all that have ever been seen. Pointing probably to two batches of around 800 cases each, 1600 total ever made.

Anyone having Altair numbers please do let me have them.
