We have received several requests pertaining to our status during the COVID-19 Virus Outbreak. Given our relatively remote location, the size of our workforce, and the fact that there are very few cases of the Corona Virus in Montana, we are continuing our regular production schedule until the State or Federal authorities tell us to shut down, or we are forced to shut down because of illness. Until such time, we are continuing to receive orders, and our production schedule and lead times remain unchanged. Should our situation change, we will notify you through email (If you are subscribed to our newsletter) and on our Social Media channels. Our thoughts and prayers are with you all and with our Country as we face the days ahead.
