Ron, I used to repair Schimels for the last 7 years but got out of the business last year. Gave all of my parts to the grandson of the original inventor but may have some seals left. I wrote four books on the schimel including a 150 page repair manual. The seals you will need depends on where it is leaking and how complete you want to go on disassembly. A complete seal replacement requires 11 seals. You could possibly get by with replacing only the two u-cup seals and the grip valve seal. I am traveling until late April so if you can not find them elsewhere contact me then. I usually sell all 11 seals for $22 shipped.
Kpaoletti, Thank you for your response. I thought I might be outaluck. Yes, I will definitely contact you late April. Would be great to have 2 seal kits and a copy of your repair manual. 11 seals, wow. I heard there were only 7.
