I recently lost the bell on my vintage OLT MKV duck call.
Out of production since 1994. Olt folded in 2004.

DJ Calls to the rescue.

Dave worked at Olt for 28 years or so and bought the inventory and machines.
Made me a new bell and back in business.

Many kick butt calls.
These are for working guys mostly.
Quality calls that are affordable.

I can heartily recommend this company.
Customer service is second to none.

There might be a couple of new calls under the tree on Christmas day.......
